In conclusion, a number of high-income countries, changes in health expectancies over time have not kept pace with the growth in life expectancy. That is, people are living longer but disability and poor health are occupying an increasing proportion of later life. Our findings suggest that countries still need to make significant progress to achieve the WHO's Decade of Healthy Ageing goal of healthier, longer lives for all. Progress on Understanding Why Human Growth Hormone Receptor Variants are Associated with Greater Longevity https://www.fightaging.org/archives/2021/06/progress-on-understanding-why-human-growth-hormone-receptor-variants-are-associated-with-greater-longevity/ A few years back, researchers noted that a common growth hormone receptor gene variant was associated with greater life expectancy in humans. There was some theorizing as to possible mechanisms at the time, following the usual paths for anything that touches on growth hormone or its receptor. In short-lived mammals such as mice, loss of function in growth hormone or its receptor produces small body size and increased healthy longevity. The present record for mouse longevity is held by a growth hormone receptor knockout lineage. In humans, members of the small Laron syndrome population exhibit an analogous disruption of growth hormone metabolism, and while there are signs that they might be more resistant to some forms of age-related disease, they do not live notably longer than the ...
