Anne: “I am giving up extreme sports now that I have children. I think I will take up golf.”
Bill: “I wouldn’t do that. Do you remember Charles? He was playing golf when he got hit by a golf-cart. It broke his leg, and he fell over, giving himself a concussion. He was in hospital for a week and still walks with a limp. I would stick to paragliding!”

In 1923, leading American zoologist Theophilus Painter declared based on his findings that humans had 24 pairs of chromosomes. From the 1920s to the 1950s, this continued to be held based on Painter’s authority,[25] despite subsequent counts totaling the correct number of 23.[26] Even textbooks with photos clearly showing 23 pairs incorrectly declared the number to be 24 based on the authority of the then-consensus of 24 pairs.
