I expect I'll get a shedload of acid responses, but I honestly think that we benefit from being exposed to a certain amount of 'germs'. I think they stimulate our immune systems a treat, and make us strong.
If we lived in a sterile bubble all the time, we'd become extremely vulnerable to any and every bug if we ever emerged.
Obviously, one has to be hygienic with food preparation etc. But this modern obsession with disinfectant 'wipes' and sterilising every single surface, item and floor is a bit mad in my opinion. It merely generates money for those companies that sell the stuff.
In case anyone thinks I'm a perfect slut, our home is clean and tidy, but not sterile!
