I also am 67, and the quality of my life at times can suck also. Due to mainly chronic episodes of PVCs and PACs. My current episode started up last night at supper and continued through the night and still now, they are bothersome.
They go away for awhile and then they come back, without any warning. It does take away from the quality of your life.
But there is support and wisdom here and like JungRulz, I wish you well and all the luck.
