Sounds like he’s never stopped contributing.
Nice story. My father is 89 and still going strong (after a little heart surgery himself.)
He had more heart surgery last year to repair a damaged valve (beware long term warfarin use!). He’s been clearing brush at the back of their property for the past week now. His only complaint right now is his knees. Given his age, he’s OK with that considering all the things that could be wrong.
I’ve got several trays of veggies started for him too. We’re just waiting for it to get warm enough to set them out now. I grow the heirlooms he likes and has trouble finding already started at the big box stores. He prefers to grow the ones his mama grew. Can’t blame him.
IIRC he’s not on any meds now either. Not even BP meds. His BP is always excellent. He was on the warfarin and statins ‘prophylactically’ given his condition and age. He’s off the warfarin now, just takes aspirin and got off the statins when he read a little more about them. His cholesterol is fine as well. Always was in fact. He was on the statins because of other ‘risk factors’ (previous heart attack). His heart attack wasn’t because of high cholesterol even. He was 100% blocked in a couple places but his cholesterol was 180 when they checked it with 30yr old technology.
