No. Don't do it.
It won't be "your little secret". It'll be a curse that'll stay with you for the rest of your life.
Let's not mess around. If you do, chances are:
You won't be able to have children. Ever.
You won't be able to eat properly for the rest of your life.
People will look at you and think you're weird cos you're so thin (it's *not* sexy!)
People will avoid you cos they think you've got something wrong with you.
And the biggest one:....you could DIE!
Yes, you could die.
If you've read this, and still think it's a good idea. Fine. Go ahead.
