I have been reading quite abit about exercise and its psychological benefits. Wondering why there isn't much out here about it.

They also say that it creates brain cells (neurogenesis) similar to that of antidepressants.(?). Changing your life = changing your brain?

Interestingly, when I was in a highly competetive sport in my late teens-early 20s I was very fit and also think it is the only time in my life I was a free-spirited 'happy' person, but maybe we all were in our early 20's compared.

Do many out here find it very beneficial? Thanks.
