I know I count as old. Plenty of people younger than me are grandparents, but I'm not yet. I don't think I'm doing too bad though. I started running in my late 40s and I think that has helped and I can outrun a lot of young people at parkrun. I see guys there in their 70s who are still pretty quick.
Ageing is inevitable though. My parents are in their 80s and feeling it, but they still do a lot.
My eyes started getting bad in my early teens, so I've nearly always had glasses. I've got a nerve issue that has affected my right hand, but I still play guitar and drums. I've only really got into playing with bands in the last few years and I love it.
I think people of our generation expect more from their older years and may have taken better care of themselves. I never smoked and I eat okay. Life can still trip you up as there is plenty to go wrong and it's pretty much a lottery. We just have to make the most of what life we have.
