Truly retiring?s

I'm turning 66 in June, had a heart attack the day I was scheduled to retire in 2002. As a result I take over half a dozen meds every day, have to watch my diet and get exercise. I also lost most of my hair. Last summer my orthpedic surgeon told me I need a new left knee and I'm an avid WALKING golfer. My 12 yr old grandson expects me to keep up with him whatever we do and take him all over the country in our MH which we do every summer. I love being active but it really hurts the last couple of years to do certain things and my bad knee has slowed me down but I won't let it stop me. I think it comes down to one's disposition; either you give up or you still have something to do with life and you charge ahead till the BOSS upstairs brings you to that sudden stop. I think I'll let Him make the call.
