BBC: Skin moles link to delayed ageing

The reason for these links are unclear, but researchers have noticed that people with large numbers of moles have differences in the strands of DNA in each cell which carry their genetic code.

Sections on the end of these strands are called telomeres, and are effectively a countdown timer governing the number of times a cell can divide to produce new cells.

The longer the telomere, the more cell divisions can take place over a lifetime - and more moles were linked to longer telomeres.
