Glad to say I'm pretty fit and healthy. No serious problems, though knuckle joints are a bit bulgy and swollen but don't restrict any activities. Eyesight poor since a child, corrected with contact lenses to give perfect vision, but my optician tells me I have beginning cataracts - but I think these have been there for decades without any significant change. I believe I have great genes - maternal family all lived into mid-90s+, not so sure about paternal side. I confidently expect to live into my 90s unless I have a serious accident beforehand.
I keep pretty active at work (s/emp gardening, lots of moving about, can get quite physical) and like going for long walks in any leisure time I have.
My mum (exactly 25 years older than me) used to say, "Look into the future. You've got all this coming!" but thankfully I don't have any of the problems she's had, either when she was the age I am now, or previously. And I show no signs of having any of the problems she has currently.
I thank God every day for my good health (which I don't take for granted). I know that some people I was at school with have already had nasty health events (like strokes and heart attacks) or have even died.
Again in the words of my mum: "Old age is not for wimps!"
