So i've been looking into all of these websites since im 20 now and gotta start taking care of my body and i stumble upon this one. It really has a lot, especially for the h8 community (who spend large sums of time sitting at their computers, LOL).
This is the link for "The twenties"
http://www.mothernature.com/Library/...ooks/43/50.cfm but it also has a lot of information on 30's and 40's etc and check out the fitness and eating right sections too.
