I really do not know anyone motoman who gets to the Buzz age group without experiencing some kind of health issue.
I agree ... it IS an age thing ... I would not have missed all the tennis/netball/gymnastics and especially the dancing that I did in my youth ... to avoid the pain I have now.
Like my wrinkles they are evidence of a life that was 'lived' and I have a whole heap of brilliant memories to sit and enjoy when it's too cold to get outside for a walk because of joint pain .... hey who on earth wants to walk in the freezin' cold anyway.
I too am not married and live alone ... that has so many blessings ... like still dancing to a good tune on the radio and no one can see you busting your best moves

... as well as drawbacks ... the thing is, you have to love yourself and be kind to yourself and take the best care you can of yourself ... like you would for a much loved partner
I do all I can to stay out of medical trouble but that's not fail proof sadly ... I try to be grateful for the good health that I have ... and thankfully it sounds like you, like me, have the security blanket of health services if needed.
And you can still do new things you enjoy that lift your spirits ... best yet Buzz is a good place to come and share
