Getting old = having more money since you already bought what you need. House, cars, what the wife needs, kids all the rest of the fun stuff!! ... i dont have kids yet but it's in the works..

Also you have already partied so hard in the younger years that you know when you can party like mad and get away with it.. So you think
And for the times you like to sit back and drink a few brewskies and play wow, either 5 accounts or more.

Everything takes time but we all get there sometime.
