Dear MEL Topic Readers,
The hidden physical powers that help women outlive men
Women outlive men by a considerable margin. For example, the average
life expectancy is around 87 years for women and 81 years for men in Japan, and 79
years for women and 73.5 years for men in the USA. It is often said that men tend to
smoke and drink alcohol more, engage more in risky and physically dangerous
activities than women. However, not all men smoke, drink, or fight. There seems
to be more fundamental discrepancies between men and women. In humans, two X
chromosomes (XX) are typically found in females, while males typically have one
X and one Y chromosome (XY). Fundamentally, XX is more advantageous than XY
because X chromosome contains more genes, which allows female bodies to have
access to a wider range of immune genes. Also, female bodies mount stronger
immune defenses and vaccine responses. And there are more physical
advantages female bodies have than male bodies do. Men and women aren’t equal,
physically and immunologically. So, why not develop gender-based medicine
and medical treatments that suit more effectively on each gender?
Read the article and learn about why women outlive men so much.
