• Question: why do we not kill 100% bacterias because on most cleansing objects clean 99.9%? is it because we need bacteria to feel sick so we feel like pain and stuff

      the adverts can’t claim to kill 100% of bacteria because they can never be sure they have got everything. we need bacteria for some things but not for feeling sick. and we only need some types of bacteria.

      No – there are billions and billions of bacteria around. We will never get rid of all the bacteria. Many of them too are good for us and help us – the good bacteria in your guts, for example.
