Did nail biting become socially acceptable recently (and if so, why)?
I feel that I have been encountering a lot of nail biters lately in my everyday life. I personally see this as one of the most revolting habits that people can do in public. I had the displeasure of sharing a 1 hour flight with a man who was biting his nails (and then subsequently running same fingers over his own scalp) for the duration of the entire flight. I shared a bus with someone who was also obsessively biting their nails recently.
