Every household cleaner and various other items like sponges seem to be sold now on the basis that they kill germs.<br /><br />I want my household germs. <br /><br />They breed immunity.<br /><br />Live in a sterile environment and you have no immunity. <br /><br />Among other things I've done the following without ever getting sick. <br /><br />Worked in shearing sheds for a few years pulling dags (sheep poo) and urine soaked wool out of fleeces for a good part of two hour stretches four times a day. Washed our hands in cold water that couldn't remove the lanolin and whatever bugs it held before eating sandwiches etc with bare hands.<br /><br />Worked as a cleaner for a few months cleaning toilets with abrasive pads with my bare hands shoved into the toilet bowl to scrub off the hard bits and push hard and soft blockages (men's and ladies' toilets) around the S bend. Nearly walked out at the start of the first shift when I was shown what to do but I needed the work. You get used to it in no time. Definitely washed my hands big time, but only at the end of a shift. <br /><br />Drank farm tank water with all sorts of bugs and who knows what dead animals like possums in it. Always best not to look into the tank.<br /><br />Ate mutton and poultry killed in the field and dressed in sheds that wouldn't pass modern building regulations, never mind health regs.<br /><br />I usually don't de-vein (i.e. remove the poo tube on) prawns before eating them. Too much trouble and they don't taste any different.<br /><br />I occasionally eat some food that's been dropped on the floor, like my last savoury biscuit, which in my squalid house is a definite dice with death.<br /><br />Despite all this the only time I've been sick for years with anything but flu and colds is this summer when I got a real nasty dose of gastro from crook water supplied to my beach shack through the mains of the local water supply authority.
