"leep and rest occupy the most time each day for both genders at allages. Men and women in their twenties spend an average of about seven and three-fourths hours a day sleeping, compared with about eight and one-half hours by men and women in their eighties. Work consumes the second greatest amount of time for men until about the age of 60 and for women until about the age of 40."
