When are American girls hitting puberty ?

12.3 years old -- this is the average age of onset for American girls hitting puberty in 2000s. American girls are hitting puberty earlier than ever. According to December 2005 issue of Journal of Pediatrics, there is a gradual decline in the average age at which U.S. girls have their first menstrual period - from the age of 12.75 in the 1960s to about 12.5 in the early 1990s. One reason: girls are getting fatter, which triggers menstruation.

person who's born happy doesn't have to try hard

50 to 70 percent of the variation in people as to their level of happiness over time is genetically determined - according to James Maddux, professor and director of the clinical psychologist training program at George Mason University, in Fairfax, Va.
The above number, I believe, applies to most of human behavior -- 50-70% of human behavior are determined by DNA, the rest are determined by how much effort they to put into it.

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.

And the 85 percent who think that these excessive payments are hurting corporate America’s image (according to the same survey).

Unfortunately, these perceptions are largely correct. Earlier this year, the Census Bureau released some statistics that attest to huge income disparities between the rich and the poor.
