I talked to my mate John the other day. He's 80. Can't stand unaided, can't walk without a walker. Has various health conditions which mean he's on morphine, has a restricted diet and is doubly incontinent.
Forty years ago he smoked constantly, drank a bottle of whisky a day, ate whatever he liked and his idea of exercise was a round of golf.
I asked him if he'd known how he would end up (and yes, most of his disabilities are linked to his past life choices which have led to strokes, heart problems etc) would he still have lived the same hedonistic lifestyle that he enjoyed from his late twenties until his early sixties. I genuinely thought he'd say 'yes, it was all worth it to have had the memories he had.'
He said no way. If he'd known how he would end up, dependent, unable to go to the toilet by himself and having to crawl up and downstairs to get to bed, he would have given up everything far far sooner.
So. Just one person's view, but his evident sadness at how he has to live now has made me think.
