Well you only become a saint after you are dead and if miracles at your grave. So the risk of being saintified and then burned at the stake is not high.
My point was just that unusual aging patterns would not put you at any particular risk of being burned at the stake.

Yep, hence points 1 and 3.
Thanks!
