I'm almost certain that Kai Greene is 40, if not 41. I hope he just wins one Olympia so he can retire. I don't want him to die. When I saw him in person, he was so thick that it didn't make any sense. I heard someone say they got that impression walking past a prime Tom Prince during an expo, and we know how that ended. Also, Kai seems to get winded pretty quickly. Another thing that is interesting about Kai is that he always stays covered up during expos.
