Happiness, time consciousness, and subjective life expectancy.

84 men and 141 women enrolled at a university reported their sexes and ages, rated their happiness and their time consciousness, and estimated how many more years they expected to live. Men significantly overestimated their subjective life span compared to actuarial data. Women (but not men) who were happier tended to be younger, had greater subjective life expectancies, and felt that they had lived a smaller percentage of their total lives. Both older men and older women tended to be more time conscious.
