Re: poll ideas quest 2017 (travel time convince)

[chacham]

You travel back in time to meet yourself. How do you know that future you is actually you?

• I have a secret word for just this occasion.
• I make up something on the spot because future me will know it immediately.
• I'll figure it out when it happens.
• Noone else would pretend to be me.
• I don't trust anybody, ever.
• I ask him for the winning lottery numbers.
• I ignore him and instead attempt to create a time paradox.
• Other

Please help with the question. I think it needs a little help.

I'd probably come up with a great plan to prove that I'm myself, do something stupid while trying to implement it, and instantly recognize my style.

If this happens to Randall Munroe, his identity would probably be confirmed before he was done explaining how he would prove his identity.
