How do you get the players to agree on whether some person is elderly or not? Some people look 10 years younger than their age, while others look 10 years older. Short of asking people for their age, it seems to remain guesswork...
It's not like it's an official competition, and it's (probably) not for money, so I imagine you can just wing it and it will be fine. If there's a disagreement you just talk it out, which is also a good way to pass time on a subway.
