An interesting topic to look into is the effect of deuterium on longevity in various species. It appears to induce a form of hormesis at low levels (perhaps) or improve resistance of certain important cell structures to oxidative damage (perhaps). [1] The company Retrotope [2] is trying to do something with what is known of this biochemistry. Deuterated drugs after the fashion of the one in this article are probably not going to be delivering enough deuterium to trigger this sort of effect, however.
