Without doing any googling whatsoever on the topic, I’m going to proffer a hypothesis and welcome comments pro & con of others’ personal observations. Hypothesis: really tall, large people don’t live as long as average sized people.
I ask this because when I was much young, I had a relative in a large senior living facility and we used visit once or month or so. I remember commenting to my parents, “Why is that all these old people seem so small?” And the response I got was, “Well, elderly people shrink.” But I remember saying, “Yeah, but do they really shrink that much? Where was the nonagenarian man who was 6’5” who shrunk down to 6’1”? Where was the nonagenarian woman who was 6’1” who shrunk down to 5’10”? Such people were MIA. Did they die young(er)? Did a larger frame correspond to reduced lifespan?
IIRC, taller people don’t live as long as shorter people. Baseball players have good mortality, football players bad, lefties bad.
