If a man is tall and imposing, he likely had a rapid growth period. That rapid growth period can leave one more vulnerable to cancer.
My son was a pretty normal height kid until almost 14 years old. He started really getting taller rapidly and was diagnosed with leukemia about that time.
When he died at barely 16, he was about 1 inch shorter than me, I was 6'2’ at the time.
I'll always wonder if there was a connection.
