As I don't have children myself (despite acting like one at 21!), I can't say that I do but if I did have kids of my own, I would make it just as much part of their lifestyle as brushing their teeth or getting dressed. We might not see the effects of bacterial infection from not washing our hands today but that's only because we have far more knowledge of what harms us and more importantly, how to prevent it immediately. Would someone be as healthy if they didn't wash? No. Would someone who washes their hands spread ailments to others just as much as someone who doesn't wash? No. Washing our hands might seem useless against all the bacteria on our food, plates and utensils but think about how much we use our hands and how much disease can spread because of it. I don't believe we should stop putting handkerchiefs over our mouths when we cough because it's anal, nor would I want someone shaking me by the hand after they've just 'dropped their cargo'.
If people can't see the point in it I have to ask in reply what's the harm in it? Soap can be expensive, especially the more popular brands, but can you put a price on hygeine? Or should we just outlaw showers because we know smells don't kill us?
Maybe I'm bias because I was raised this way by a mother who has been in the medical profession all her life, so I suppose it's natural for me to think like this. A good question though, Bethperry!
