From FuturePundit, some thoughts on where you should be looking to see progress in implementing the next stages of regenerative medicine and enhancement built upon growing use of stem cells: "Professional athletes are not risk averse. The doping in baseball and by athletes in other sports demonstrates the huge health risks they'll run in order to win. Plus, they have big dollars to spend. Imagine that Michael Jordan could have gotten his knees fixed with stem cell therapies. He could have made millions more by playing more seasons. If athletes can find ways to take risks with stem cell therapies then stem cell therapies will advance more rapidly. I am also expecting plastic surgeons to embrace a lot of experimental stem cell therapies ahead of the mainstream medical community that treats diseases. The plastic surgeons mostly market to people who pay out of their own pockets. This gives them more flexibility. ... Once stem cell therapies for injury repair start happening then expect to see the therapies take off for rejuvenation. A bad joint from hard football tackles needs some of the same kinds of repairs as a bad joint from decades of wear and tear in the bodies of the elderly. ... Once a substantial market develops then part of the research to further improve treatments will get funded from cash flow."
