Some research has shown that if either of your parents had their height development restricted by diet, it is a trait that can be passed to you (quite a violation of inheritence).
I'm sure I read it in Newscientist..
The weird thing is I always thought this was how cattle was brought up, until I saw a documentary on TV about an outbreak of food poisoning and they showed how these beasts really live... in their own squalor and waste
If you're getting sunburnt then yes, as it means your skin is damaged!

Burns leads to cancer..
Cancer leads to suffering..
Take this as a personal anecdote, but I'm short sighted and my eyes become worse during the exam period.. every exam period! I don't think its because of anything specific like TV or a computer monitor, but staring at anything in close range for long periods of time. It's probably genetic as well.
i'm not sure.. but apparently chemically produced saturated fats (like margarine) often contain chemical bonds that are completely unlike anything produced in nature. I think it was "trans" double bonds or something?
Not really..
I think the closest thing we have is testosterone patches - more aggression in all aspects of life, be it on the road, at work, or .. in the bed.
Don't we have fields because simply because we can't reduce everything down to its essence? Imagine trying to do behavioral work on animals based purely on biochemisty. Or another step up, studying the sharemarket using biochem! Not quite there yet..
And you might as well go the whole way...
