Men are gaining on women in life expectancy

82.6 years is the current women's life expectancy, shown by a study released from Credit Suisse First Boston this week. For men, it is 78.1 years, 4 years short. However, over the last two decades, men have increased their life expectancy at twice the rate of women. Reasons: 1) women are working and getting more stress from it. 2) women took up smoking about 25 years ago and are now dying from it. I guess this is the price of equality between men and women. But experts say men will never catch up, because risky behavior is in their nature.
