This thread is hysterical ...some people need to stop worrying so much ...(unless you have someone immune supressed etc)
Washing hands in public toilets/ hospitals etc is important because you are being subjected to a wider range of 'germs' -they have come from a wide number of people ...
The only germs in your house really are those belonging to you/your family ...(assuming no/few visitors) so unless anyone in your family has a stomach upset you are pretty safe not washing your hands...
For those worried about germs getting onto toothbrushes/ splashing loo seats etc - I had salmonella - admittedly I did try to do good handwashing - but suspect that after almost 24 hours crapping water every 30 mins or so, sleep deprived and weak - my standards may have dropped slightly -but no-one I shared a flat with got it ...
Out of interest - wash your hands with anti bac soap and put it on a petri dish and leave it to grow (sealed) - there will be fewer bacteria present - but shock - there will still be some!
Things like threadworms - they are so easy to transfer if one of your dcs have them you are just as likely to get them from inhalation etc...
I would say you were more in danger of getting ill from not washing your hands after touching the lid of a food waste bin that hasn't been cleaned for a week in your kitchen...than by not washing your hands after a wee....
Just remember - anything that comes out of your bottom went in through your mouth!
(Just if they survived going through you they are more likely to make you ill - and will probably be in larger nos)
Finally do you wash your hands after touching money? - that is really gross stuff ...has been handled by lots and lots of people ...
(after having to count it - especially lots of notes - it stinks... coins smell metallic but less unpleasant than notes...lots of notes together smell (to me) of stale sweat....)
