See, I've been trying to put on wieght for years, and rigidly follow the "sofa-diet", but to no avail - what am I doing wrong

There has to be a certain level of geneticism involved too...if you come from a fat family, then chances are , you're gonna be fat. But hey, it doesn't always follow that just because you're fat, you're unfit - who's gonna tell Samo Hung, that he's unfit...err...not me!
