Sex gap in life expectancy and healthy life expectancy [1]. The male-female health survival paradox, also known as the morbidity-mortality paradox or gender paradox, is the phenomenon in which female humans experience more medical conditions and disability during their lives, but live longer than males.
Some studies suggest that red and blond hair are more common in females than in males (red more so than blond). In lighter-complected humans, male skin is visibly redder; this is due to greater blood volume rather than melanin. [50] [51] Conversely, females are lighter-skinned than males in some studied human populations.
Scientists may have found the reason women live longer than men. A study found men’s life expectancy in the U.S. is six years less than women’s.
Researchers found that people worldwide live 9.6 years longer than they are healthy — and in the U.S. the gap is more than 12 years. The U.S. has the biggest lifespan-health span gap in the world.
In 1950, the average American life span was 65 years, he pointed out during a panel he spoke at called “Navigating Longer Life Spans.” Today, it’s more like 77.5 years—an almost 13-year gain.
A smaller fraction of adults die at 20, at 30, at 40, at 50, and so on across the lifespan. As a result, we live longer on average... In every way we can measure, human lifespans are longer today than in the immediate past, and longer today than they were 2000 years ago... age-specific mortality rates in adults really have reduced substantially."
The study, which was presented at the American Society for Nutrition's Nutrition 2023 conference, found that people who adopt eight healthy lifestyle habits by middle age can expect to live longer ...
For instance, Pacific Ocean rockfishes have widely varying lifespans. The species Sebastes minor lives a mere 11 years while its cousin Sebastes aleutianus can live for more than 2 centuries. [48] Similarly, a chameleon, Furcifer labordi, is the current record holder for shortest lifespan among tetrapods, with only 4–5 months to live. [49]
