/there have been study after study showing that by putting your fingers into your mouth, you are actually tranferring millions of germ into your body. They say you should wash your had several times a day and always use soap as this will cut down on the chances of getting sick from the gern on your hands and fingers. Imagine where and what your hands have been and touched during the day, Wash your hadns often.

Alright, so we can nibble our nails to our heart's content if we wash our hands first! I'm only kidding, MilkyWayExpress!

I wash my hands after handling money - you never know where it's been! And when I return home, one of the first things I do is wash and dry my hands, because I never know what I might have touched when out, and then forgotten about, like door handles and railings and even dogs and cats. No, it's not germaphobia, but just a good precaution to take, especially during cold and flu season.

The absolute best way I know of for cleaning my hands, and under the nails as well, is to work the shampoo through my hair extra-well when I wash my hair every morning. This seems to work better than just plain hand-washing or even soaking my hands, for removing all dirt on my hands and under the nails.

Yep you can bite away as long as you wash them hands, hehe.
Joking aside washing our hands like you described is the best way to prevent infections from getting into out bodies. I probably was my hands more than a dozen times a day just to be safe. Of course then I have to use a moistureizing cream to help with the dryness as well, I have extremely dry skin.

Guess,in a strange way I'm lucky that I rarely get sick...with an overactive immune system. I'm sure my nails are just thrilled I continue to chew 'em :-)

I do though wash my hands pretty regularily. With working full time(being in public),a full house load of kids(lots of germs there too),I'm still pretty careful on ensuring cleanliness.

I did some research and found out that your oral and gastric acids kill the germ and pathogens that enter your mouth. We are exposed to billions of pathogens every nanosecond of life on this planet. Besides, I am a constant nail-biter and don't worry about germs.
