I will attempt to answer this question with an anecdotal (true) story ...
I've lived here for slightly more than a quarter century. I have known my neighbors across the road, since their children were entering secondary school, a very long time ago. Two years ago, on a Saturday, I was over there standing at the front fence chatting with the wife of the couple. She had been a local heath care provider for ~43 years (wearing various hats) and had retired 2 months previously as an APRN. She was in absolutely tip-top medical shape, worked out regularly, had two adult children (both retired from different branches of the US military), and two grandkids (that visited occasionally). The following day she was being wheeled out to an EMS unit with a stroke. No prior warning of any kind. Of any person I know, who cared for their health as much as she did, she was the last person I would have expected that would happen to. Because of the type of stroke, she had no ability to communicate, nor consciousness. She was effectively on life support. Several days later, once the entire family had gathered, and based on her explicit advanced directive, there was full agreement to terminate life support. All organs were donated. Several months later there was a memorial service, with a wake the following day.
At the time that happened, she was 5 months older than I was. That experience made me laser focused on both managing my health, and on making sure that I am doing things I want to do. Not sure what else to say, other than enjoy your life while you have it. Life is precious.
