Wikipedia is wasting me and I fail at this research thing apparently :((
-- thanks everyone who took the time to reply! I think I'm going to go ahead with a theoretical 17yrs old. As it's really only a passing mention and I need him pretty youngish ;D I've been saying in reply to some of you guys, that I kind of wish I was doing more with all this information you've supplied me with! I'll definitely be keeping it all in mind should I ever need any info on this subject again- you guys are awesome! Thanks again.
