- Ear wax is actually a combination of substances.
- Glands near the external ear canal produce cerumen (comes from a Latin word that means "wax").
- That substance then combines with flakes of skin, sweat, and oil.
- Mixed together, that's ear wax. Delightful, isn't it?
- Ear wax can range in texture from almost liquid to firm or nearly solid.
- The moisture content of ear wax is an inherited trait.
- This means that people originating from different parts of the globe have wax of different consistency.
- European-origin folks have moister wax, while Asian-origin folks have drier wax.
- Wax can also range in color, from a very pale yellow, to a deeper yellow, to reddish brown. The darker the wax, the longer it has been in your ear.
Cerumen is produced by glands that line the ear canal.
The cerumen mixes with skin and sweat and body oils and becomes ear wax.
Then it travels the canal away from the ear drum (tympanic membrane) out of the ear.
(Diagram owned by Northwestern, used by Dr. Timothy Hain)
- Aided by the tiny hairs that line the ear canal, ear wax will travel out of the canal to the outer portion of your ear.
- Once the wax reaches that outer portion, it will dry, turn flaky, and fall out.
- You should not use Q-tips to clean the wax out of your ears, tempting though it may be. This is because, while the swab will collect some of the wax at the outer portion of the ear, it will push even more of it back toward the ear drum.
- If you get enough wax pressing up against your ear drum, you will start to have trouble hearing, and you may even wind up with a perforated ear drum.
- In addition, the wax helps to keep dirt and bacteria and other nasty things from traveling the ear canal to the sensitive and crucial parts of your ear. If you have removed the moist wax from your ear, there will be little available to combat those nasties, and you are more likely to get an infection.
- Ear wax build-up is the number one cause of hearing loss. But most of the time, that wax build-up is caused when the ear's owner has used some pointy object like a Q-tip to try to remove the wax and has succeeded only in jamming the wax farther into the ear.
- So unless you want to give yourself an infection or hearing loss, don't stick anything pointy in your ear! I know it's tempting. Believe me, I do.
- If you really must get that wax out of there on your own, you can try these methods:
- Put a few small drops of mineral oil (baby oil) or olive oil into your ear. Let the drops sit for a few moments, then tilt your head the other way to encourage the oil to slide out. Rest your head on a towel -- no need to jerk yourself around -- and allow the oil and excess wax to slide out on its own.
- If your ear seems to be really plugged, you can try those ear wax removal kits from the pharmacy. Follow the directions on the box closely.
One commonly available method to remove ear wax at home.
(You can buy this product for $8.19 from drugstore.com)
- You should never try either of these removal techniques if your ear drum is perforated.
- It can be hard to tell if your ear drum is perforated, or ruptured. But here are some signs:
- Sharp, sudden pain in one ear
- Sudden drainage from the ear that is pus-filled or bloody
- Hearing loss, often accompanied with pain
- Ringing (tinnitus) in the ears, often accompanied with pain.
- If your ear wax is dark brown, don't confuse that with blood. Ear wax turns brown when it gets old, and that's perfectly normal. If that was blood coming out your ear, you'd know it.
- If you think your ear drum has been ruptured, go to the doctor. Don't stick anything in there, not even ear drops. Let the doctor take a look and decide what treatment is necessary. Most ruptures will heal on their own within two months. But in some cases, the doctor might tell you to wear a patch over your ear to keep out infection or to take antibiotics, or the doctor might recommend surgery.
- Here's one last ear wax fact for you: in medieval times, monks used to use ear wax to smooth out the pigmentation for illuminated manuscripts. Resourceful, eh?

I love the speed of it, the way the wind rushes past my face. At the same time, I'm going slowly enough that I can look at houses and people and all sorts of interesting things as I ride by. In that way, biking has all the benefits of walking, in that I feel like I'm physically part of the neighborhoods I'm moving through, not like when I'm in a car and securely wrapped in my metal bubble. But I'm moving faster than walking, so I can cover more territory. But mostly it just feels good.
You can ride a bike just about anywhere.

I've been really wishing I could remember hand signals. Sometimes there are cars behind me, and I don't want anyone to have to guess about anything. I remember that if you want to turn in one direction, you stick your hand straight out. Another direction, you hold your shoulder straight out but raise your forearm perpendicularly in the air. But is that for a right turn or a left turn? Because I couldn't remember, I was just pointing vigorously in the direction I meant to go.
Turns out, that weird signal is out of fashion. You could still use it if you wanted to, but apparently most people are like me in that they can't remember which way that's supposed to indicate.
LEFT TURN -- hold out your arm straight to the left.
(Diagram from Dr. James Watrous)
RIGHT TURN -- hold out your arm straight to the right.
This one is much more obvious than the other, so I'm only going to post this one.
(Diagram from Dr. James Watrous)
STOP -- hold out your left arm and drop forearm toward the ground.
I can't imagine using this signal very often. Mainly because I need both hands to work the hand brakes.
(Diagram from Dr. James Watrous)
Some other bicycling safety tips:
- Ride as far to the right in your lane as possible. Sometimes potholes or parked cars make it too dangerous or difficult to hug the curb, but try to keep to the right as far as you can.
- If you're going to make a left turn, do a head check first. This acts as a kind of signal to traffic that you mean to move out into the road. When the traffic is clear, move into the left turn lane (if there is one), and once you're in that lane, keep to right of that lane as you make your turn.
(Diagram from Bike Miami Valley)
- If there is no left turn lane, wait at the right side of the right lane for traffic to clear, and then cross the right lane and make your left turn.
- If somebody told you to ride your bike against traffic, they gave you bad advice. Always ride with the flow of traffic.

It's The House With a Clock In Its Walls, and it's one of my favorite books, ever. Yes, it's for young adults, but a good book is a good book no matter what age it's for. If you haven't read it -- and if you like the Harry Potter books -- you should definitely check it out.
The book is about a shy, overweight kid named Lewis Barnavelt, whose parents are dead and so he moves to a small town in Michigan with his large, bearded, mysterious Uncle Jonathan. Uncle Jonathan's house is old and full of strange objects like umbrella stands and mirrors that display strange images -- all of which make sense when Lewis discovers that his uncle is a wizard. Not only that, but the house used to belong to a different wizard before Uncle Jonathan, a malevolent wizard. The previous wizard hid a clock somewhere in the house, a clock whose ticking becomes louder and more threatening as Halloween approaches, and Lewis must find it.
Lewis Barnavelt, as drawn by Edward Gorey
That's the plot. But there's more. The book's author, John Bellairs, has an easy touch in creating the likable overweight Lewis, the gruff but loyal Uncle Jonathan, and the eccentric neighbor Mrs. Zimmerman who likes purple. Along with the suspense that makes me say out loud things like, "Uh-oh, that's bad," and "Ooh, I knew he shouldn't have done that," Bellairs manages to convey a coziness, with people eating chocolate cake and playing cribbage in the evenings.
I first read this book long ago, back in yon Apple Lady's youth, and then a few nights back, I was at a friend's house, perusing her bookshelves, and I saw that she had several books by John Bellairs. Excited, I asked her about them. She said, "Dude, John Bellairs rocks."
She, too, had read The House With a Clock In Its Walls in her younger days, but she had also read many of his other books, and these were what she had on her shelves. She flipped through a few of them, showing me that Edward Gorey had illustrated some, and that Mercer Mayer had illustrated some others.
"I opened this one up," she said, pulling The Figure In the Shadows off her shelf and turning to a picture of a boy stealing another boy's Sherlock Holmes cap, "and this picture took me right back to fifth grade."
She was kind enough to lend me two of her Bellairs books:
The Figure In the Shadows is a sequel to The House With a Clock. In this book, Lewis is being bullied and though his friend Rose Rita tries to stand up for him, he is ashamed that a girl is protecting him. He finds a magic coin in an old trunk of his uncle's and discovers that the coin gives him a strange sense of new-found power. But soon, the coin begins to exert other powers as well. . . .
The Curse of the Blue Figurine is about a different young boy, Johnny Dixon, who lives in a small town in Massachusetts with his grandparents. He goes to Catholic school and discovers in the basement of the accompanying Catholic church a mysterious blue statue with a note warning that anyone who removes it from the church will bring vengeance upon his head. Nervous Johnny is startled by a noise in the basement, so he runs out of the church still holding the figurine, and now he's in for it.
I read both of these books this weekend. I liked them both (though I liked Lewis and his uncle a touch better than the bookish Johnny), but I also noticed enough similarities that I started to wonder about John Bellairs. Both books were set in the 1950s, both of their main characters went to Catholic school, both boys got picked on by tougher kids, both boys were orphans in some sense.
So let's see if I can identify some similarities.

Lewis Barnavelts’: New
St. Mary’s Roman Catholic
Johnny Dixon’s: St. Michael’s Roman Catholic
Lewis: Fat and moon-faced
Often alone, “scaredy-cat”
Johnny D. and Lewis B: both bullied by bigger, tougher boys
Johnny D: complimented on his reading abilities
Joined Latin and Chess clubs
Lewis: knows Latin quite well
Johnny: plays chess with the professor across the street
Grandmother died 1951 (John was 13)
Lewis: both parents dead
Johnny: mother died of cancer, father fighting in the Korean War
Johnny Dixon lives in
So, yeah, a lot of things in common between the author as a youth and his young leading men. And he's even acknowledged those similarities in various letters and interviews.
"The heroes of my books are loners and outsiders because that's the way I felt when I was a kid," Bellairs wrote in a letter. "If you're fat, brainy, can't play sports and are physically cowardly, you don't fit in." -- Bellairs
"Writing seems to be (for me) a way of memorializing and transforming my own past. I write about things I wish had happened to me when I was a kid." -- Bellairs
(Photo from Calculo's page on John Bellairs)
Bellairs died in 1991 of heart disease. However, author Brad Strickland was asked by John's son Frank to complete four of his father's books that he left unfinished. Strickland also wrote three new books based on Bellairs characters. Reminds me of what's still going on with V.C. Andrews -- writing from beyond the grave.
Thanks for the books, John B!

An Australian company called Unicraft Joinery has come up with a way to make storage space out of stairs. Apparently the idea is not new, but I still think it's ingenious. The comments about this particular concept are additionally enlightening and entertaining.

They seem like such quiet creatures, but so many of the seemingly-silent ones turn out to make some sound, so I wondered if that's true of turtles, too.
The short answer is yes, they do, but the noises depend on whether you're talking about a turtle or a tortoise.
So, first, the differences between turtles and tortoises:
Some people say tortoises are a type of turtle. Other people say there really is no distinction between the two in a strict classification sense. But then they all list the following differences anyway.
live in salt water
live on land or in fresh water
awkward walking on land
not good swimmers and could drown
have blade-shaped flippers
have legs rather than flippers
Now, for the sounds of turtles & tortoises:
These turtles are not in the water at the moment; they're taking a break from it. You can see their webbed, flipper-like feet, which indicate their preference for swimming rather than walking.
(Photo from Snail's Tales blog about bugs, animals, and other oddities)
- Turtles have no vocal chords, but they do sometimes make other sounds.
- Hissing: when turtles pull their heads into the shell, sometimes they emit a soft hissing sound. This is not actually a vocalization but the sound of the air in the turtle's lungs as well as the air in the shell being expelled as the turtle's body moves into the empty space.
- Gurgling, bubbling, whistling: If a turtle makes a gurgling, gargling, bubbling, whistling, or wheezing noise, the turtle may have a respiratory infection, and the sound you hear is the sound of fluid in the turtle's lungs. If you own a turtle and it is making sounds like these, check the humidity and temperature of your turtle's environment to see that it's appropriate for your turtle's needs.
Tortoises tooling around on land at the Santa Fe Teaching Zoo
Larger tortoises have been heard making various noises, including vocalizations.
- Tortoises also make a hissing noise when they retreat into their shells.
- The Radiated Tortoise, which only lives on the island of Madagascar, will make a high-pitched noise if it is caught, sometimes for hours afterwards. Most predators would be so startled by this disturbing sound, they would release the tortoise.
- Forest Tortoises have been heard thumping their heads on the carapaces of other tortoises, as a prelude to mating.
- Galapagos, Forest, and other tortoises have been heard grunting during mating. Others have described the Galapagos' mating cries as roaring or bellowing, loud enough to be heard for hundreds of yards. Only the male makes sounds, and only during mating.

I now have one of the worst sunburns I've ever had. It is not the worst because I left as soon as Clinton stopped speaking. I knew I was getting burned -- my skin looked bright red through my sunglasses though it looked the same without my sunglasses -- and when I scratched near my collarbone where the skin is thinner and very sensitive to sun, it stung. As soon as I could, I practically ran to get out of the sun. But this burn is pretty bad. Some six hours later, my skin is deep red, flaming hot, and tingling and prickling. I'm also feeling slightly nauseous. Bleah.

- Apply sunscreen about half an hour before you go out into the sun.
- Make sure you pretty much glop it on. Most people don't put on enough sunscreen, or they apply it too thinly.
- SPF = the ratio of the amount of time it would take for protected skin to get a burn vs. the time unprotected skin would burn. SPF 15, for example, is supposed to mean that if you wear sunblock with SPF 15, it would take 15 times longer before your skin burns than without sunblock. But that ratio is usually not accurate because many people don't apply sunblock correctly, or it washes off, etc.
Relatively new sunscreen products, all with high SPFs
(Photo from Blog This Next's pages on sunscreens)
- Most doctors recommend sunscreens with SPFs of at least 30.
- No sunscreen is waterproof. If it claims to be, it is lying. It can be water resistant, but it will not be waterproof.
- There are so many problems with sunscreen that packagers are no longer allowed to call it sunblock, only sunscreen.
- Choose a sunscreen that protects against UVB and UVA rays, a.k.a. "broad spectrum" protection.
- Sunscreens are good for a minimum of three years. But if you use the product properly and as often as you should (any time you're in the sun for more than 20 minutes), you should use up a bottle of sunscreen long before three years have passed.
- And by the way, there is no safe way to tan. Whether you're in the sun or in a tanning bed, you are damaging your skin and increasing the likelihood of giving yourself skin cancer.
- There really are no good ways to treat a sunburn once it's happened. This is why sunscreen is so important. The best you can do after the fact is try to make the pain and heat a little less severe.
The best stuff I ever used after a sunburn was a blue aloe vera gel. I can't remember now the exact name of the product, but it was something like this. Except this has Lidocaine in it, to which some people are allergic.
(Photo and opportunity to order from Drugstore.com)
- Things you can put on your skin to ease the burn:
- Equal parts milk and water on a cool compress.
- Aloe-based lotions.
- Or, if you have an aloe plant, you can split open a leaf and scoop out the goop and put it right on your skin, though it takes a lot of aloe goo to do very much. The aloe lotions are much easier to use and provide more coverage.
- Even regular moisturizers can help.
- Cool -- not cold -- baths or showers. If you do take a shower, you'll want to avoid a strong spray.
- You can also take aspirin or an NSAID like Tylenol, which can help reduce the pain and some blistering.
This person's shoulder was sunburned so badly, blisters arose. This blistering means he sustained a second-degree burn. If you burned your hand on the oven, say, enough to get a second degree burn, you'd take that pretty seriously, wouldn't you?
(Photo posted at Gadling.com)
- Things that will make your sunburn feel worse:
- Lotions with oils or Vasoline, which will trap the heat to your skin
- Old fashioned "treatments" like butter or toothpaste -- these will make the pain worse!
- Products with perfumes which will be irritants
- Bath salts or bath oils
- Scratchy towels or scrubby things like loofahs or sponges
- More sun exposure
- Also, products with anesthetics such as benzocaine or lidocaine (Solarcaine, e.g.) can trigger an allergic reaction
- You should go to the emergency room if your sunburn is so extreme you experience the following:
- Severe pain and blistering
- Severe chills
- Rapid pulse
- Nausea, even vomiting
- Fainting (a.k.a. sun poisoning)
- If these things are happening, you have sun poisoning.
- If you don't go to the hospital, you'll risk contracting an infection at the blister sites. What is more likely is that you could get severely dehydrated and lose way too may electrolytes, which can throw the body into toxic shock. You do not want that to happen.

Here's the article I just read about his retirement.
And here's an Apple I did a while back about Bob Barker.
Sunday, June 3, 2007
Last night, I did not complete my usual mission. I started this entry on Sunday (hence the Sunday time stamp) but could not finish it. We had an enormous thunderstorm, and after it passed and turned into lightly trickling rain, my cable went out. For two and a half hours. Then it was bedtime. So this entry is a day late. To those of you who rely to any degree on reading this on your Mondays, I apologize. But at least you have something new to read today, yes?
Now, on to the entry itself.
So, the last time I went to the grocery store, I bought some pistachios.
You can buy these roasted pistachios for about $6.75 a pound from Nuts Online.
(Photo from Nuts Online)
I've been eating them in my lunches at work and as a snack in the evenings. I have to eat them with two hands, to pinch open the shells and sometimes pick off that brown coating over the green nutmeat. Because it takes two hands, I therefore concentrate on what I'm doing, which led to me think about the nuts I was eating.
It struck me that these nuts are unique in many ways:
- The shells are split open already. We don't eat any other nuts (that I know of) that are already open. I think if I came across a walnut or an almond that was split open as much as most pistachios are, I'd be inclined to distrust it. But if the shell of a pistachio is mostly open, then I think, mm yum.
- The nuts are green. Again, I would normally associate the green color with unripeness. Not so with pistachios.
- They're salted in a different way than, say, peanuts are salted. The salt on peanuts seems to be more granular, but the salt on pistachios is more of an all-over coating, or maybe a dusting. I'd like to know how they get that salt on there.
- Used to be, pistachios were almost always dyed red. Where did that idea come from? Why red?
You see? Many observations, many questions.
- If you get a pistachio with the shell unsplit, it means the nut is not ripe. Shocking, yes, but true. Somehow, somebody must have gotten this fact across to me because I do regard split pistachios as looking very good -- besides the fact that the unsplit ones can be a pain to open.
- The nut -- technically "the kernel" -- expands as it ripens until it splits the shell. The California Pistachio Commission recommends discarding unsplit pistachios because that means they are unripe. But then, the CPC would have an interest in you throwing away your pistachios, wouldn't they?
Those closed-up ones really aren't as good as the already open ones.
(Photo found at the Foodgoat blog)
- The green in the pistachio kernel comes from chlorophyll, the same thing that makes plant leaves green. Why the kernels are green as opposed to brown, which is true of most nuts, I don't know. I guess we'll have to ask the pistachio trees, and they're not talking.
- Growers prefer kernels that are very green as opposed to yellow-green. Probably the yellow ones don't look as ripe.

They look good to me full-out naked like this, too.
(Photo sourced from Feed Me I'm Hungry's entry on 3 dishes to make using pistachios)
- Before 1976, pistachios were not grown in the US but were imported from the Middle East (mainly Iran, Turkey, and Syria). Companies that harvested the nuts there used "antiquated harvesting methods."
- It is true that if the nuts are picked but then are not processed for 12 to 24 hours, the shells get stained and spotted. So it's possible that those pre-1976 nuts were stained because the producers took a little too long to get to the roasting.
- In any case, the US importers decided to dye the pistachios to hide the evidence of "antiquated harvesting." They decided that red was the right color, since it would make pistachios more eye-catching compared to other nuts. So that's how they got turned red.
- Some pistachio-eaters are still partial to the red color, so some pistachios grown in the US are still dyed red using vegetable dyes.

- I found a recipe for roasting and salting pistachios yourself, and I suspect it's the same method, on a smaller scale, by which pistachio processors get that really fine coating of salt on their nuts. Here's the recipe:
- Add 2 to 3 ounces of salt to 1/2 cup of water (4 ounces).
- Pour saltwater into a deep saucepan over high heat and stir to dissolve the salt.
- Add 8 to 10 cups of pistachios and stir until all the water is evaporated and the salt remains on the nuts.
- Transfer the salted nuts to a cookie sheet and roast in a preheated 250 degree F oven.
- Roast 1 1/2 to 1 3/4 hours, stirring about every 30 minutes.
These pistachios were grown and are being processed in Iran, the nut's homeland, so to speak.

- Some research was released lately that says eating pistachios helps reduce stress. As with all these medical studies involving food, however, that does not mean you can go out and shovel truckloads of pistachios down your throat and expect to be stress-free.
- The research showed that people who ate a small to moderate amount of pistachios (1.5 ounces per day, or about a handful) showed signs of the lowest amount of stress, where people who ate more pistachios (3 ounces per day, or about two handfuls) were only slightly less stressed out than the people who ate none.
- So as always, beware those articles with the headlines that proclaim that this or that food will make you happy / skinny / avoid heart disease / sexy / stress-free / taller / fill in the blank.
- Keep pistachios stored in an airtight container, or they will get soft (as I myself discovered).
- You can freeze the nuts, too, and keep them that way for months.
- Pistachios are related to both the cashew and the mango.
- Pistachios are not actually nuts but are drupes, which are fruits with a single seed. In other words, stone fruit, like peaches, apricots, plums, cherries -- and mangos.
- A pistachio tree does not produce nuts until it is at least five years old. It reaches its full nut-making capabilities somewhere between age seven and age ten.

- Many pistachio trees in the Middle East are hundreds of years old. One pistachio tree in Iran is still producing at a ripe 700 years old. Another in the Ukraine's Nikitsky Botanical Garden is 1,000 years old, but I don't know whether it still makes nuts. Here's a photo of a gnarly 1,500 year old pistachio tree in Greece.
- Only the female trees produce pistachios. The male trees produce the necessary pollen.
- A new pistachio tree, about 3 to 4 feet tall, will set you back about $28.50.
- It took US growers 47 years to figure out how to raise pistachios as a crop. Seeds were first brought from Iran in 1929, and people planted and experimented for years before they got the trees to produce like their Iranian ancestors.
- For tips on buying, growing, and harvesting a pistachio tree yourself, check out Eagle Ranch Pistachios' Tree Information pages.

- You can shake, knock, or pick ripe nuts from the tree. The California Rare Fruit Growers association says, "A single shaking will bring down the bulk of the matured nuts." I like the idea of standing under a pistachio tree and shaking it so that all sorts of nuts come raining down.
