85 year-old golfer
George was 85 years old and played golf every day to a really decent standard. He came home one day and told his wife: "I have to stop playing golf. Although I still hit the ball well, my eyesight is so bad that I can't see where it lands". His wife tells him to take his neighbour, Harry, with him. Although Harry was 103, his eyesight was perfect.
On the first tee the following day, George hit a perfect shot, straight down the fairway. "That felt good," he said, "did you see where it went, Harry?"
"Of course I did," replied Harry, "I've got perfect vision."
"OK then, where is it?" said George.
"I can't remember" said Harry.
