Just out of curiosity, I'd be very interested in hearing comments about how reliable this study can be:
http://cebp.aacrjournals.org/content/16/7/1499.long
"Nevus Size and Number Are Associated with Telomere Length and Represent Potential Markers of a Decreased Senescence In vivo"
(it is also offered in free full text, available at the link above)

It sounds very strange to me that a skin blemish can affect senescence (although I would like it to be true since I have many moles on my body)..
