We will have to disagree on this. You are determined to see everything
about telomeres are supportive of your "sacred" theory. I see this
example as so different that is could be taken as quite refutive of the
telomeric theory of human aging (although I did not imply that, I only
said it was unrelated).

Except that there is extremely little evidence that it has *any*

Nonsense! You have no valid grounds for that statement.
I think we should quit this discussion (at least *I* am going to). We
have now beaten it to death (I notice Aubrey has already dropped out)
and we are just spinning our wheels at this point. Unless, you (Tom
Mahoney) have more evidence to present, I am finished until I do more
reading and deep delving on my own. If you have all the papers, I would
appreciate copies to read, thanks.
