Review: What is a supercentenarian?
Jeanne Calment lived to 122
Born in 1875 — fifty years before electricity was used in
homes …yet she lived until the age of the internet! And at the
age of 120, she released a 4-track album “Mistress of Time”
Ate 2 pounds of chocolate per week
Loved olive oil, and drank wine and port after meals
Smoked until the age of 117
