people who think iti is cool don`t do it for the same reason as people who are hurt and want sort of physical release...

but i think that they don`t quite know what they are doing to themselves..it`s a BAD habbit! cool...well..wahtever...
i can undestand where it`s coming from and i think there may be a reason maybe even a subconcious 1 for them to think it`s cool...not a normal 1......
