Eighty percent of flavor comes from your nose, including a set of internal nostrils. When you chew food and hold it in your mouth, the gases that are released goes into these nostrils. People who wolf their food are missing some of the flavor.
There are fast chewers and slow chewers, long chewers and short chewers, right-chewing people and left-chewing people. Some of us chew straight up and down, and others chew side-to-side, like cows. Your oral processing habits are a physiological fingerprint.
Chew on this: Human teeth can detect a grain of sand or grit 10 microns in diameter. A micron is 1/25,000 of an inch. If you shrank a Coke can until it was the diameter of a human hair, the letter O in the product name would be about 10 microns across.
I love words, but I also love finding out that there is a word for something that you've experienced but didn't know there was a word for. Like 'toothpack' - that is a word for when you eat biscuits or cookies and you get that annoying layer of chewed substance on your molars that you kind of have to pick out.
Weightlessness was unbelievable. It's physical euphoria: Nothing about you has any weight. You don't realize that you are weighed down all the time by yourself, and your organs, and your head. Your arms weigh down your shoulders. In space simulation, you get to fly like Superman! You're hanging in the air! It's the coolest thing.
I spend a lot of my time on the phone, pestering people. 'What's new in your lab? Can I come visit your lab? When can I come visit your lab?' I'm basically a professional pesterer.
I've been writing full-time since about 1984 - mostly magazine features and columns.
Editors are more concerned with the first chapters of a book; that's what everyone reads first in the bookstore or in the online sample.
Fletcherizing is gross. I tried it once. I tried to go until it's all liquid, and it just creeps you out to be focusing so much on your chewing.
Flatulence peaks twice a day... five hours after lunch and five hours after dinner.
Saliva has antibacterial properties. It also has things called nerve growth factor, skin growth factor, histatins which help with wound closure. So when you see an animal licking a wound or even a mom kissing a child's boo-boo, there's some, there's some good science behind why one might do this.
People are surprisingly off put just by saliva, the substance that you carry around in your mouth. You swallow it. You have no objection to it. But then it leaves your body, and you're just revolted. So it - that - just that right there to me is a fascinating thing.
I've always been a bit of a space geek. I wrote an article years ago about the neutral buoyancy tank, which is this biblically sized pool where they train astronauts. And it was just the coolest thing.
We exist in this weirdly schizo culture, where sex is everywhere in the media, and yet, at the same time, you don't sit down and have a conversation about what you did in bed last night with your friends. Despite the ubiquity of sex, it's still a taboo when it comes to day-to-day conversation.
