Maybe, as people have suggested, being naive and childlike produces some kind of anti-aging effect on the body. Aging is primarily the result of free radicals damaging the body, which are present in the air we breathe, as well as in food, etc. Various substances can neutralize and/or protect us from free radicals, it would be interesting to see if we produce some kind of hormone along those lines. Anyway, people usually think I'm about 25. This should be nice, but the whole process of convincing them I'm really 42 and I'm not lying, gets old, and things can get awkward when they find out I have a 16 year old before they find out how old I am, and they start doing the math, and looking confused and distressed. It should be funny, but it just gets old. I'm sure it doesn't help that I'm very short, I'm still wearing a ponytail and docmartens, and you are more likely to find me in a bookstore or an ice cream shop than in a bar or a club.
