I bite my nails. How can I keep proper hygiene in the kitchen?
Gloves are annoying and, much like condoms, do obscure sensation and--in the case of kitchen work--precision with your fingers. For those reasons I avoid them wherever possible.

As a lifelong nailbiter (from when I was about 9 until I was 31), it was a habit that was really hard to give up. But it has been worth it, not just professionally. I know this isn't the answer you're looking for, but: stop biting your nails.
