- andyjsong 4y agoI've been known to pump my leg rapidly like in the video when I'm anxious. Maybe it's an involuntary artifact to "keep the engine running" just in case my flight senses are triggered.
- gcanyon 4y agoI definitely don't do that tapping motion instinctively. Unless I'm actively doing something, I am naturally still. Ten years ago I found out I have Factor V Leiden, which can cause blood clots. Since then I've consciously tried to develop the habit of toe-tapping.
