I stand by what i say, i dont think Gunter will come back better than before, for the sake of the arguements for and against lets hope he does. I think the break is too long to be beneficial at 40, i believe after such a break, his body ability to control cortisol in a way in which his body once did will be decreased, so having fresh receptors wont matter as i believe with age what finishes guys off as they get older in this sport is not the bad response to hormones as we age but the drugs ability to control cortisol levels in the body as they once did. Just an opinion, i cant back it up with science just an observation.
