Women are more famous for it, but men certainly trim a few years off here and there as well. The bad news is that it seems that stress speeds aging
at the cellular level: high-stress women had shorter telomeres than lower-stress ones. This probably goes for men too, but was not tested. Potentially also bad for those unwilling to reveal their real age, is research into developing a better lie-detector
using fMRI. I'd like to see more detail on what areas are involved, but this could potentially be both scary and really promising.
