Nervous habits can manifest as habits such as nail biting, head bobbing, throat clearing, or finger drumming. Though you might not realize you’re doing them, these behaviors aren’t exactly involuntary like the tics experienced by people with a condition like Tourette’s; a big difference between a pathological tic versus a nervous tic is that when asked to stop a nervous tic, you’re able to do so.
