ADD: not to mention that a hard workout causes your body to produce endorphins during stress situations whose sole purpose is to dull pain by drugging you into feeling "happier"
You've probably heard about it before when people talk about getting a "runner's high", etc.
Probably the reason why 3/4 of the fatass nerds on the net are so cynical and hate their lives is because they never work out.
And then you bring in shit like their self-confidence and self-image and their outlook on life just goes to shit. I see it everywhere i look on the net.
You'd be surprised how much more positive and happy you'd start feeling if u just got up off your ass and started working out.
