In comparison, the potential exposure to BPA from use of dental sealants on a child of average weight, based on the assumptions above, is 0.037 milligrams per kilogram of body weight. This exposure level is more than 50,000 times lower than the LD50 values that have been reported for BPA.
U.S. expectancy in 2011 was 78.7 years, which is slightly below the OECD average of 80.1. For U.S. men, the average life expectancy is 76, while it's 81 for U.S. women. (At five years, this gap in life expectancy between men and women is smaller than the OECD average of six years). The U.S. life expectancy comes in just behind Slovenia, at 80.1 years, and Denmark, at 79.9 years.
Any individual woman can vary quite a lot compared with an average.

The average age of menopause depends on the population studied to calculate the average.
