At the moment my wife and I are lucky. As far as we know (!) , we have nothing much wrong with us. I still have a few things that are longer term after effects from my 2013 stroke, but compared with many I have been lucky I know. Most of me still works!
As we age, several of our friends have died or now have serious illnesses. My interest in sex has dropped off and the death of others no longer seems so odd. I recall a doctor once asking me (probably 10 years ago) "if it was all too much" and I retorted "no". If he asked me now I am less sure.
Although I find so much to be interested in, I get exhausted more easily and I am tired of being giddy most of the time. Life is harder than it was.
