At least a couple of the companies mentioned in that article appear to be out of business. The prices quoted back then are non-trivial for middle class Americans.
It still seems like the sort of thing that might be worth the expense. If they come up with the solution when I'm 80, but I don't have any source of young stem cells to rely on...
Same goes doubly for my kids.
