Why tricking the nature is so often the first reaction of people around here? Sleep helps replinsh brain cells - let's make a pill that does just that so we don't need to sleep as much! Vegitables are good for you - let's have a pill that has all their nutrients so we don't need to eat them! Exercise betters the mood - let's isolate those chemicals so we don't need to exercise! Being barefoot is good for you - let's all buy "barefoot shoes"! I really don't get it. Why are people so averse to natural ways and ofetn simple moderation. I did not grow up in North America, so maybe it's just a cultural difference.
