Nope, you're describing not being young, that's nothing like being actually old. Growing old has a bunch of stages:

• joint pain

• can no longer dance all night

• hangovers last all day

• dentists start talking to you about your gums

But then you get to the phase of

• skin losing elasticity

• liking dinner parties

• marijuana is now a medicine

• developed distinct preferences about stuff like threadcount

And then after that the next phase is more like

• a lot of time worrying about your parents

• all body fat migrates to one or two of its favourite spots

• seriously consider putting everything on lanyards

• your favourite singers are all dead

And so on, you get the picture. That's as far as I've traveled but as far as I can see the phases after that involve things like bladder leakage and losing friends to alzheimers.
