Snippet on JeanneCalment's lifestyle

Calment smoked from the age of 21 (1896) to 117 (1992), though according to an unspecified source, she smoked no more than two cigarettes per day.

Calment ascribed her longevity and relatively youthful appearance for her age to olive oil, which she said she poured on all her food and rubbed onto her skin, as well as a diet of port wine, and ate nearly one kilogram (2.2 lb) of chocolate every week. Calment reportedly remained mentally intact until her very end.-link

A nice snippet. Regarding some factoids of the lifestyle of the longest living human yet, as of this posting.2.2lb is about 10 100g chocolate bars per week!
