Hey Apollo. I know looking young can have it's downside but it also has it's good points. I'm 40 and look like I'm 28. When I was in my 20's I would:
Travel for free on public transport as a student. Would walk on with my backpack and no-one ever questioned me.
Haggle by saying, "How much?, oh mum only gave me $X, I need to talk to her. Go back 10 minutes later and say "Mum couldn't give me any more sorry." Then get whatever with my original $X.
Tell the people knocking on the door looking for me to sign the Electoral role that mum and dad weren't home at the moment.
Cheap entry to movies, Royal Shows the Zoo...lots of things
etc, etc
I know these things might not suit everyone's situation so it's more to encourage people to get creative.
If you've got it use it I say. Balance out those downers
