I have a temporary solution for anyone feeling old.
Me and a friend, every year, we take a week's holiday, and get together, and just screw all responsibilities and catch up on playing games, watching dumb movies, and eating delivery pizza, junk food and soda, all just sat in our pants, for most of the week, and I tell you, you really feel about 15 again! It's so nice also to play a few co-op games with someone in the same room
It's far cheaper than going on holiday just to sit in the sun, tho we both do that as well something, but just for one week a year we both regress back to when all we had to do was go to school then play video games.
