A small cluster of stem cells in the brain seems to help mice stay young, and injecting extra stem cells helps them live longer. The hypothalamus, which releases hormones that affect other organs, seems to affect how mice age.

Anthony and Jeff discuss this event, and wonder if they can be forever young.
