I have to say that everthing the first five posters said has happened to me. This past week I turned 69 and consider myself in marginally good health. The only meds I'm on is a low dose blood pressure med. Recently had what I call an "old persons" procedure done on the veins in both legs to increase blood flow and stop my feet from swelling. It seems to be working and I should know for sure within a month when I go back for a post op exam.
What really makes me stop and think about my mortality is that in the two years since I moved to Florida from Pa, 19 of my friends and acquaintances have died. Some older than me and some younger. But most within 5 to 7 years of my age. I get the obits from the newspaper from where I came from and from friends via email and Facebook.
In the meantime, I'm trying to enjoy life as much as I can as a free man.
