Women,why do some of you wax?

I cant imagine waxing ANYWHERE.I have hairy azz legs and when I tear off a band-aid it hurts like f*ck.So why do you sometimes wax?Isn't it the same as shaving except a lot more painful.Yea why do some wax if you could shave.Does it last longer?Is it better for skin or what.I have no idea.
