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.
Men tend to die younger, bringing down the averages. The average 65-year-old woman today can expect to live another 19.8 years or a total of 84.8 years. If she makes it to 75, she can expect an additional 12.6 years or a total of 87.6 years. Men don't do quite as well, but the difference shrinks as they age.
