I must confess to being a complete doubter -- until yesterday morning.
I did a MEDLINE search on progeria, a syndrome marked by hyperaccelerated
aging. Much to my surprise, several references had found reduced DNA
repair activity in cells from progeria paper. Not a smoking gun,
but quite suggestive (I didn't save the references -- sorry).
