      Hi Afaf

      No, smaller animals tend to age ‘faster’, and have much shorter lifespans, than humans.

      No, usually small animals tend to age faster. There is this theory, called rate-of-living theory, that says that the smaller an animal is the faster it metabolism is the shorter is the life span and since small animals have a fast metabolism they live less.
      I personally have doubts about it and I think new studies proved it wrong…. but it’s a theory!
