I am no doctor, so i won’t be recomending doing any of these things.
But if you have any of these habits, don’t worry to much about breaking yourself of them. If someone asks just tell them i said it was ok.
I’m someone who must constantly be doing something. I’m guilty of flipping my pen around my fingers and clicking them way too much. My knees are always bouncing up and down while I sit, and I will tap on every surface I get a chance to.
But these kinds of fidgeting can be good to burn small amounts of calories throughout the day (sometimes over 300 calories). You’re not burning enough to replace exercise, but it does help our metabolism to use up stored fat.
