Hopefully never...
I reckon the only thing that's changed in the last decade is I have more money. I also have a house but that's probably because I couldn't find a landlord that would let me build dirt jumps in the back yard!
Life's to short to get old, become compliant, worry, stress, sit down and relax, go to bed early, watch tv, etc... Ok, tv has nothing to do with it - just kind of fit the list.
Actually if anything makes me feel "grown up" it's watching the people around me get old!
Children get told what to do - not adults. As an "adult" I feel I am old enough to determine what it means to be an "adult". Don't let societal norms determine what it means to "act your age".
