Well, I do think if I had Parkinsonism or some other dreadful disease and I had a lot of life in me yet to live, I might look kindly on a stem cell.
There is something to be said for living in perfect health until one drops. But part of the marketing of stem cells, is about extending the natural life span. I don't like that aspect. That is really letting the genie out of the bottle. Heck we could have a Senate with 100 Strom Thurmonds.
