The longest known lifespan of a person is that of Jeanne Calment, who lived to be 122. In addition to that, she:
Claimed to have met Vincent van Gogh when she was 13 - though nothing can be known for certain, the claim was likely. She lived her entire life in Arles, which van Gogh had then been visiting, and she was working at her uncle's fabric shop at the time.
Smoked until she was 117 - an exception rather than a rule, needless to say.
Aged 90, agreed with a lawyer to sell her apartment to him after her death, and the lawyer would pay her a monthly sum of money. Not only did that mean the lawyer lost a lot of money, but the lawyer died two years before her!
