lol, i was skinny in High School, about 5'9" 160 lbs, not as skinny as some here, but i did not look menacing...anyways, if you want to gain wait, drink CytoGainer, it's a muscle milk protein mix...lol, and junk food, like $1 double burgers if you can find any...should do the trick, and video games really work!!!!!! i'm 22 and i'm a solid 5'11" 200lbs!!!!! good luck man, but i didn't start gaining weight till i was like 20...i had a very fast metabolism!!!!!!
