Except that telomere shortening is no longer a valid hypothesis; no real evidence for this has been found. In fact the ability to generate stem cells from adult cells completely negates this theory. Telomerase studies have been important and got their researchers a Nobel prize recently (only the creator of the theory was as usual not found among the laureates), but telomeres do not really shorten during life.
Do you have a citation? That contradicts everything I can find published.
