Getting old is a privilege not afforded everyone . . . but it ain't for sissies !
Glad you got a good report - pacemakers are a lot more compact than just a few years ago and maintenance/adjustment a lot less invasive.
I survived my "widow maker" heart attack and then a few years later got titanium knees, so I'm satisfied to keep from having to add any other 'bionic' features as long as possible.
