Key Info
  • The bacteria living on our skin
  • Duration: 00:56
  • If we looked at our skin through a microscope we would see tiny crannies and crevices. Inside these tiny crevices millions of bacteria are living and growing and they double their population every twenty minutes! It is a short and dangerous life for bacteria as the surface of the skin they live on is continually eroding. We shed skin all the time and with it we lose 25,000 bacteria a minute! Most dust in the home is really flakes of skin complete with bacteria!
