Dont get me wrong, I have nothing but respect for the golden age wildcat. He was a boxer, using his fighting abilities against crime.But I forgot who it was excatly but I remember that the whole JSA was given some extra strength and vitality by a super villin. But then extant took all that away and aged the jsa back to normal in zero hour right? Ok, not green lanter, flash I can see them being able to fight in the jsa because of their super powers. but if wildcat is just a regular 60yr old guy right? Even if he is in the best possible shape of a senior citizen, isnt he a lil old to be putting on the suit? If therse something Im missing here clue me in.
Since he debuted in the 1940s I'd say he has to be at least 80 by now, probably closer to 85. I think the added vitality granted in the Ian Karkull storyline is all that's needed to explain the aging. If his aging was slowed in his 20s until just a few years ago (Zero Hour probably happened "5 years ago" in DC time) he may still be a man physically of 40-50, who knows. I don't know if he really became his true age after that or if he just started aging again at a regular rate but is still at that younger age.
I thought the 9 lives retcon was basically to establish how he was healed after Crisis on Infinite Earths when his legs were "shattered" by lightning and we were told he would never walk again. I didn't think the 9 lives curse had much to do with his retarded aging but maybe it was a catch-all explanation. After all, the rest of the JSA all had fall-back explanations for their retarded aging after they lost their Karkull juice. Hawkman's aging was slowed by Nth metal, Alan Scott's by the Starheart, Jay Garrick's by the Speed Force. Why not Wildcat's by a magical curse?
