Telomeres and Older Fathers

Interesting story about the effect of paternal age on telomere length.  Do you find that telomeres generate a lot of discussion and interest among your students? Does anyone have any interesting activities to share?   Anytime you can bring in aging and cancer, the kids really seem to get engaged.  http://www.sciencedaily.com/releases/2012/06/120611153109.htm
