Chew your fingers

It's free food so why not!

This is normal for some people but it can lead to toe nails the inside cheeks and lips as well as pulling and eating hair such as eyebrows and eyelashes and scalp hair.

Haha I was doing it right when I ran into this post. Lol. I think it's pretty normal..At least common.

It's not good but it's normal. I admit that I have that awful habit too:/

I did, but now I just bite my nails.

Normal, not healthy. You can get skin infections, scars, etc. Just think about everything you touch during the day: keyboards, shoe laces, books, door knobs, food packages, trash can lids, yourself & other people. Would you lick any of that stuff?

It's normal if you're a hungry cannibal.

Normal. I use to do it but stopped on account that it damaged my teeth.
