Isn't this a fine can of worms...
Late last spring, my wife and I signed up for the Anti-Aging program offered at ProSports Club in Bellevue, WA. (Now that we have moved to Portland, I really miss the ProClub—it is the largest sports club in North America, just a really fantastic place to train. The spinning classes [about 4 times per day] would frequently have 20-40 folks in for the class, and they had about 75 spin bikes in that room. The place had 2-3 dozen individual "personal trainers", a staff of 6 MD's, lots of physical therapists, and several different buildings. There is nothing similar in Portland.)
Anyway, the Anti-Aging program mostly follows protocols of the A4M (American Acadamy of Anti-Aging Medicine). The key being bio-identical hormone therapy which for me does include bio-identical testosterone supplementation (not the same as the synthetic low-T products advertised on television). The goal is to get your T levels back to what they would typically have been 10-15 years prior to your current age. At this point, about 8 months into the regime (which also includes vitamin supplementation and lots of blood draws to monitor levels) I will say I do indeed feel 10-15 years younger than my 56 years. I get up without aches and pains, I have much more energy, and I recover faster from training. In my case, my doc typically won't begin to add Secretropin until after a year on the bioidentical hormones. This is because often the body will begin to elevate the HGH naturally as a response to the other hormones being supplemented. In my case, the last blood work showed the natural HgH had risen substantially from my prior blood work a couple months prior.
I will add that, while I have not been training much, I have been able to get through the stress of buying and selling a house, moving to Portland, and having my business contents (and also my stereo gear) stolen during the move—without getting sick. My sweet wife wasn't around much to help as she was in corporate housing in Portland for a couple months, so I basically covered the move and my business alone. There were times the stress level was pretty damn high, and I think if this life event would have come before we started the BIHT (bio-identical hormone therapy) the stress would have taken a much greater toll. (I do think having been in pretty great shape headed into the move helped a lot too.)
And I can drink wine with less impact in the morning!
My wife thought I looked funny carrying around Susan Summers book "Bombshell", but she's probably the most visible and vocal advocate. Her book is worth reading even if you come away with differing opinions. I'm a believer in this approach to wellness, and personally I don't see too many folks aging "gracefully", but instead I see most folks getting up in years having more and more ailments. Now that I have the resources, I don't want to age out before I have the chance to do so many of the things I couldn't afford as a youngster.

My sit bones have been aching the past 3 months or so, really cramping my rides.
