May 15, 2013 — Women’s immune systems age more slowly than men’s, suggests research in BioMed Central’s open access journalImmunity & Ageing. The slower decline in a woman’s immune system may contribute to women living longer than men.
Researchers looked at the blood of healthy volunteers in Japan, ranging in age between 20 and 90 years old; in both sexes the total number of white blood cells per person decreased with age. The number of neutrophils decreased for both sexes and lymphocytes decreased in men and increased in women. Younger men generally have higher levels of lymphocytes than similarly aged women, so as aging happens, the number of lymphocytes becomes comparable.
but why even in younger years females have higher doctor bills than males?
Young women’s doctor bills are higher than males mainly due to childbirth. As this is a normal process, the greater expense does not represent poorer health in this case.
