Q

Why do we age? 4 theories.

A
  1. Supply limits: decreased supply of nutrients to cell
  2. Free radical damage: uncontrolled build up of free radicals
  3. Autoimmune: B & T cells weaken w age, then malfunction
  4. Programmable cell death: signals induce or suppress apoptosis
  5. Telomere length theory: Cell division permanently destroys tiny fragment of the telomere w each cell division
