Respect your elders
Sogen Kato was believed to be the oldest man in Tokyo up until 2010 when officials finally entered his apartment and realized that he had died at the age of 79 in 1978. His death had been kept a secret by his family who were collecting his pension. This lead to a huge search for all people over 100 years, and it turned out that Japan couldn't document the whereabouts of 234,354 supposed centenarians.

A few years ago Grandpa John had a heart problem and had to be taken to the hospital. His heart rate was 20. With a heart rate of 20 you shouldn't be conscious, but he was smiling and joking and just his regular old self. The guy who was doing his paperwork came over to him to ask him some questions. Name, insurance, address, that sort of thing.
When they came to his birthday he said: "July 6, 1915." The paperwork guy wrote it down, then did a double take. He looked at the form, and looked at Grandpa John. Then he stuck out his hand to shake. "You're my first!" he said. Grandpa John grinned at him, shook his hand, and said "Congratulations!"
His heart rate was still 20. Everyone was shocked he was still conscious. That evening he had a pacemaker installed. Still doing great, and is one of the nicest people you'd ever want to know. Looks like a guy in his 80's in good health.
