My granddad has been lucky to have relatively good health, but since turning 90 things are so hard for him, again even with relatively good health for his age. He can't commit 100% to a lot of things as some days he's just not up to anything, it's hard for him to enjoy holidays like he used to as he can hardly walk anywhere. I feel really sad to see him living like this - I wouldn't want to. And I know I'm not going to be one of those 90+ years old doing yoga or whatever, as I have a joint problem so my mobility's probably going to be shot relatively early. I think I 'd rather go by my mid-80s thanks.
