Turned 73 now, much the same build as when 18, and apart from a sometimes achey elbow (bust it twice in my youth) no medications, etc, and feel fine.
There is the 'Triple A' swollen artery thing in my abdomen though, which I do have ultrasound checked every year.
I try not to do anything too strenuous... as recommended by the doc, but if it blows it blows. Nice knowing you all.
