This information is after talking to a lot of people over a period of time:

The question asked was "If you could be young again, what would you wish your age be?:

A 23 year old girl: I would like to be 18 again.

A 30 year old who works at my client site: I'd like to be 22 or 23

A 40 year old guy who plays rac ball with me: I'd like to be 30 again man!

A 50 year old cab driver: I want to be 18 again (Yeah whatever!!)

A 60 year old bus driver I met just a few minutes back: I want to be your age!
