My dad didn't either. I think it was the first brick wall of his life and he didn't know how to get past it. He went downhill after a surgery that was supposed to make him more mobile, not less.
All you say in this thread is so true. Once you lose things it’s hard to get them back. Better to try to keep them by pushing yourself.
Hospitals are often the absolute worst places for old people’s health.
My dad was in pretty bad health, and had dementia, but could walk a kilometre or 2 and look after himself a little bit.
He then got a nosebleed that wouldn’t stop and had to spend a week in hospital.
When he came out he had aged about 5 years. Could only walk 100m with sticks and that took 15 mins, could hardly stand up from his chair and suffered a lot of cognitive decline too.
6 months later he got covid and had to go into hospital not because he was particularly sick, but because it tipped him over the point he couldn’t stand.
He spent a few more weeks in hospital before dying, but we basically knew as soon as he went into hospital he’d never get out because being inactive would weaken him so much he couldn’t get his strength back.
Because of his many health issues it sped up the process so much you could see the decline so clearly in real time, but it absolutely showed me the importance of keeping active and pushing yourself as much as you can.
