There's finally an answer as to why women typically live longer than men, and it all comes down to the cells.Scientists in Japan have discovered that as men age, they produce fewer infection fighting T-cells, and less B-cells (producers of antibodies) than women. It probably doesn't help that the female body is actually designed to be more long lasting than the male. Over time, male bodies begin to break down more rapidly; making them more susceptible to diseases.Thanks, science.

The life expectancy for men in the US is 75.35 years old, and woman 80.51.
