This may be the only 50/50 game there is and it was to stop aging.

It was the 21 or 12 game I played, I said to my mom to pretend that 21 and 12 are both equal that it is not the same as just taking 12 and saying 12 because that is the one that comes first in numbers and that you pick one and don't tell me which one you say and to say what number 21or 12 I have down on the paper and my call was 21 and she said 21 and I won it on the first prob important try for the first time this way 30min ago. I am 27 yrs old, I done this game from all just me.
