OK, I admit it, I'm a hair twirler. I did a little online research and have determined that ultimately, I'm not a crazy person. Phew. Basically, it's fairly common and harmless as long as I don't graduate to a hair puller. I don't see that happening at this point in my life, thankfully. Bottom line? Hair Twirling is a "comfort habit", like a security blanket. Twirling occurs when one is tired, anxious or engaged in passive activities. Females are more likely to twirl than boys because we've got more hair!
