I used to floss daily. But, I then learned that it has very little health benefit *if you brush your teeth a couple of times per day*. If you don't brush, flossing is very beneficial. But, brushing does 99% of the job. So, flossing on top of brushing doesn't do much. Nowadays, I floss when I have something stuck in my teeth, or if I notice the floss when I'm not busy, and decide to give it a go. I probably average 1.5 times per week.
