Discussion: Women, on average, around the globe outlive men between 6-8 years. A similar phenomenon exists in many other mammal species. What is the explanation for this phenomenon?

The fact that women live longer than men, probably thanks to much better liver functions, sharpens the enormous importance of the liver in preventing inflammation. It is precisely the problem of fibromyalgia patients suffering simultaneously from multiple inflammations in different systems. The answer is that the liver of fibromyalgia patients is very weak! Since the liver has no pain sensation, most patients are unaware of their poor liver function.

Some of the gaps in women's and men's life expectancy are also due to gaps in lifestyle, employment, and diet, but this is a widespread phenomenon in almost all species of mammals. Therefore, the explanation must be more biological. The female hormone estrogen, secreted during a woman's fertility period, protects the liver. A long lifespan requires a robust immune system. The liver and kidneys directly affect the physiological system as a whole; therefore, a more vital liver provides a longer lifespan. The explanation for the phenomenon is evolutionary. Females play a crucial role in childbirth and raising offspring, so nature has given them a significant physiological advantage. On the other hand, the male hormone testosterone enables a rapid increase in muscle mass. However, physical strength in the modern world is unnecessary for survival and does not increase life expectancy!
