Personal Habits .-- According to Hufeland and other authorities on longevity, sobriety, regular habits, labor in the open air, exercise short of fatigue, calmness of mind, moderate intellectual power, and a family life are among the chief aids to longevity.

Such are farmers, gardeners, hunters, soldiers, and sailors.
In these situations man may still maintain the age of one hundred and fifty or even one hundred and sixty.
Possibly the most celebrated case of longevity on record is that of Henry Jenkins.

This remarkable old man was born in Yorkshire in 1501 and died in 1670, aged one hundred and sixty-nine.
