My father wore a pacemaker for his last 20 years, NJC. His only complaint about it was that it didn’t have a gear shift on it. When he need it to go faster, it wouldn’t. The year before he died, I called him one Saturday when he’d said he’d be home. He didn’t answer–and I called him at least 10 times throughout the day. I finally called my brother, who lived nearby, and asked him to drive down and check on Dad. Around 8PM, Dad called and said, “WHAT?” I told him I’d called him all day long and he said, “Was that you?” I asked why he didn’t answer the phone and he said, “I’m not getting down off of the roof to answer a phonecall!” (Dad never had a cell phone.) It seems he was up on his own roof putting down new shingles…at age 84! Carrying them up the ladder, too.
