Just thinking, back in The Christmas Invasion, the Tenth Doctor got his hand chopped off, but it grew back since he was within 15 hours of regeneration. That severed hand would later play an important part in The Stolen Earth/Journey's End by absorbing his regeneration energy and therefore prevent regeneration from completing. Of course, that led to the creation of a clone, but that's beside the point.
So, then it would seem obvious that having just regenerated, the Eleventh Doctor should cut his hand off, have it grow back because it's within 15 hours of regeneration, and then keep the severed hand somewhere safely. That way there, should he ever be mortally wounded, he can stave off regeneration by having it absorb the energy. Of course, he could also end up with a clone as well, but that's beside the point.
Thoughts?
