It's all just common sense, that people don't want to accept, you'd be amazed at how much a simple thing like stress for example can affect your health. I've been learning that recently with my work, dental hygiene for instance it turns out is particularly affected by stress and I found out awhile back thanks to a really good dentist who spotted the problem that I was grinding my teeth in my sleep.
As for all the other shit, yes, eat your fucking vegetables and go and exercise, people are just lazy and don't want to do it and if you don't have the time to exercise you really need to make some and put your foot down.
