Re: SPOILER ALERT: Anyone bothered by....
That's another good point. I felt something was off in that somehow but it didn't hit me until you pointed it out. Logan is in his 30's now. He was in his early teens (or about) when it kicked in but he kept maturing to a point then stopped aging.
Would it have really reveresed Yashida's age if he gained the power? It certainly would have repaired the ravages and damages of old age and years of his body going through life without it but he shouldn't he just be an exceptionally fit 90 something year old man?
