Re-take the oldest photo of you, standing in the exact spot

Dig out the oldest photo of you that you can pin to an actual spot — a doorstep, a school gate, a sea wall — and go stand exactly where it was taken. Line up whatever's still in frame and take it again: same crop, same angle. You're really there to check on the background — what survived and what quietly vanished, which you can't know until you're standing in it. Lampposts outlast everything; the shop next door probably didn't.
