might want to think of "life" a bit more before you go face, eye lids, etc. you also might want to consider some serious drugs; you are nuts for thinking its an "experience".
Pain is an experience. Have you done a hanging before?
And no, I don't have a lot of tattoos. You are right, though, in that a 9 hour experience is much different than a small tattoo that takes little time.
Also, what is up with your use of quotations at the word 'life'? Might want to consider "life"? Plz elucidate.
