When I was a child, I had this persistent belief that I will live forever. Recently, I have been thinking if living forever is indeed a tangible thing or science fiction. To understand and think about ways of delaying or stopping ageing altogether, we need a solid definition of what constitutes ageing first. Without having any claims of being an expert in the field, I am going to try and present a comprehensive definition of the process and discuss some interesting directions in the field.

I recently had to write a Summary of our work on telomere biology in planarians for the public, so I thought I would post it here as well, as its likely to missed on a dusty beurocratic website somewhere.
