I have heard others say that growing old is not for the faint of heart and that is very true.
I learned a lesson from an aunt and uncle of my wife's. They scrimped and saved all of their working lives and claimed they would be quite the travelers after retirement. Once they retired, their health started to fail and there was no traveling. The only thing they really accomplished by scrimping and saving all of those years was that their kids will have a great inheritance.
If there are things you want to do, and can do so without bending the budget too badly, then its time to do them.
