I've found that most geeks i've met really arent lean at all. Many are just slightly overweight, but generally average... that said, i'm rather lean. When i was a kid it was worse, i used to look like a skull with skin stretched around it. You could see the muscles in my face move.
Also, 5 in the morning is late for anybody, unless you're on night shift.
Humans aren't meant to be alone, but they are meant to splt up and spread out into other places. That's probably one of the ways humanity spread across the world... that and the simple curiousity in exploration
either way things turn up roses eventually... i think...
