Beer Tabs: On or Off?

Whenever I crack a can of beer my next move is unusually to twist the tab on the can, and break it off. I’d be a long time since I finished a beer without taking the tab off. I don’t really have an reason for doing it. I suppose it might get in the way of your drinking a little. Its probably mostly because I’m a really fidgety person.

Do you take the tab off of cans? Or do you have your own habit with your beer cans?
