These supercentenarians have given advice to people on how to live long and how to live happily. Their ages have been documented with varying degrees of authenticity. For example, Christian Mortensen and Jeanne Louise Calment are recognized by Guinness World Records as the oldest man and woman respectively, though Almihan Sayit in China says she is 127. Whatever their precise ages, these people have walked the Earth longer than most, and are able to look back on many experiences and distill some truth.
