(HealthDayNews) -- How long do you expect to live? If you're a woman, you'll probably accurately estimate your life expectancy in line with national averages. But if you're a man, you're likely to give yourself a few extra years.
That's what the department of sociology at Ohio State University found when surveying 2,037 people and comparing their estimates with life expectancy tables.
As reported in the journal Social Science in Medicine, women were generally accurate but men tended to be optimists, and anticipated three years more than the statistics indicated.
African-Americans expected to live six years longer than the tables predicted.
