I do know about healing times as i tore my bicep 2 years ago, i was unable to train for over 6 months! There is also a risk that it may tear of when you start back training its a bummer!
Yes it is on ya mums side not sure about it skipping a generation tho, if ya mum has a brother & he's bald well get yaself a wig or do what most bodybuilders do these days shave it off far better than stickin a rug on ya head!
Hell no the first thing newbies down the gym ask these days is can i get hold of some AAS to get massive? Sometimes even b4 they've even started at the gym or know what the hell there doing! Its getting worse every day i see 160lb guys wasting their time doing gear, because they either don't...
