Some people like to sing to their radio (ok, I enjoy that as well), but for whatever reason I tend to get the sudden urge to floss while I'm driving. After several days of just wishing I had some floss sitting around on my way to or from work or running, I put an extra roll of it in my car. The way I see it, flossing in the car is better than restricting myself to flossing only in the bathroom at home and then never remembering to do it.
Yesterday, on my way to run club I was flossing it up and everyone I passed seemed to notice. I received many grins from passersby on my two mile route and I hope they all have a new outlook on the productivity that is possible while driving. Granted, it's not always the safest and sometimes I'm driving with one hand or an elbow, but I haven't been in any fender benders yet and I haven't tried flossing on the freeway.
Besides, the next time you go to your dentist, don't you want him or her to say "it's obvious you've been flossing?"
