Analogies:
The hayflick effect is like something being used more than it can handle, before it can't do its original job anymore. Such as, reusable stickers. They may re-stick over and over, but after a certain point they will stop sticking.

In the News:
[|Hayflick limit] [|Leonard Hayflick] in 1965 discovered the **Hayflick limit** during research at the Wistar Institute in Philadelphia, which was an observation that cells dividing in cell culture divided about 50 times before dying. [|Cellular Senescence] Because cells are the fundamental building blocks of our bodies, it is logical to assume that cellular changes contribute to the aging process. In this essay I review the methods used to study cellular aging in vitro, in particular replicative senescence, and debate whether these findings could be related to organismal aging.
