My last venture, Workstride.com, was sold to Riverside PE at the end of 2012. I've always been interested in stopping or at least slowing the aging process. As a lifelong software guy, coupled with plenty of evidence from parabiosis experiments, I believe lifespan is programmed by natural selection, based on a species’ resources, predation and stability of their environmentThe main mechanism for determining lifespan is a naturally occurring, blood born peptide called GDF11. Interestingly enough, the molecular structure of GDF11 is maintained across all vertebrate species. You have GDF in you right now, but unless you are 18, you don't have enough of it. GDF11 production ceases at age 74 which greatly increases your rate of aging and makes it very difficult to make it to 100 and beyond.GDF11's mechanism of action is repairing stem cell DNA, HOX gene reactivation as well as tumor surveillance/eradication. GDF11 declines with age, so as you age, your stem cell populations diminish and atrophy, eventually resulting in catastrophic failure i.e., death. Injecting endogenous GDF11 can stop this process and my goal for the last eight years has been to refine the GDF11 dosage and replacement process.Check out my latest GDF11 talk at GDF11Rejuvenation.com -> About. At my recent RAADFest conference presentation, I explain some of my recent GDF11 research including completely reversing BPH and plaque as well as curing canine cancers.
