A very fun thing to do in your older years would be to fabricate or adopt the life of someone rawther credentialed.
Maybe an astronaut, or someone senior in government, or a former spy.
You could then get invited to fancy parties and tell raucous stories about famous people. Mostly you could drink too much free wine, be hugely inappropriate, and not give a damn because “don’t you know Who I am?!”
You could change all the wiki photos to look like you in your youth, just in case any one Googles you. Get some fake business cards with gold crests and “for lords sake” tell lots of stories – especially about drinking with Prince Philip and Elton John.
Then just go trailblazing your way around the city.
It wouldnt be a half bad retirement.
