True, you continue down the same decay path - except you can constantly be
restored to an optimal state on it.  Gain weight when you're 30?  Keep
being reset to 20 and don't wait a full decade before the next reset.

Further, link this to gene therapy.  If genes can be identified such that
removing them results in babies who are less likely to become obese, this
becomes a suitable vector for introducing said genes to adults, slowly
replacing all their cells.

That said, I was talking about organ-by-organ replacement as an upgrade
path (as an alternative to whole-body-at-once redesign), not specifically
stem cells.
