I've posted this a few times here over the years: my brother was an elite level athlete, even at the age of 62. He suffered a massive stroke that has left him seriously disabled. His life changed in an instant. Almost unimaginable for someone in his physical shape.
On the plus, before his injury, he had never deprived himself of much. He traveled extensively, skied all over the world, dined at the best restaurants. While he "died" in a way, he has those memories and there is never a "gee, I wish I had done XYZ".
You just never know.
+1 Throughout our life, even with young kids and a much tighter budget, we made it a point to take at least one vacation each year. Last year, at age 69 I had 5 stents, despite being a regular exerciser of running, swimming, etc. DW and I went to Europe a short while back, then Florida....and now I'm under "house arrest" due to pericarditis. All is good now, but no exercising for a while. I'm glad I got those trips in, and we already have plans for November and next year. I didn't save all these years to not spend money I can afford.
