Oh really? As if being alive now isn't enough proof that you were alive a few years ago? usually people don't magically appear out of thin air.
How does a tattoo prove you were "Alive"? People get tattoos all the time and it proves little more than the fact that they got a tattoo. I see people with tattoos all the time and I've never looked at it and gone, "Wow, that person was really alive before he killed a part of his flesh and filled it with ink".
Sometimes people prove they were alive by telling a story about their tattoo, but that's more in the story than in the tattoo.
Your motivations are hilarious.

Maybe you should consider carving a statue because when you're finally dead(the time I'm assuming it owuld be important to prove how alive you were) the skin has a habit of decaying.
