Dude, can you use proper grammar, PLEASE? It gave me a headache to read your post. Even sumit's posts are easier to read than your garbage.
Plus, what you wrote is something most of us already know.
Point well taken. Next time I'm writing something at 3 in the morning, I should proofread it first
As to your second point, you're right, most people do know this. But common sense is not common practice. Everybody KNOWS they should be eating healthy and exercising regularly. Seen any overweight people lately?
