My Mum (Mam) is 88 and still jumps on the bus to go shopping.
Needs to bloody slow down. Suffers from anxiety, gets lonely has to be doing something (bloody moved that to me).
Call her a few times a day which drives me nuts but I know She lives for the calls. My Brother luckily is local thus sees her regularly.
Back to the retirement theme. She lives like She is still in the war.
Only yesterday all worried that her washing machine is packing up. Then She states as bright as a button, “I bought it on the 23rd of June 1999.”

Easily survives on the state pension and a very small private one.
