Deficiency of growth hormone and IGF-1 reduces cancer and kidney disease, but creates other problems

...6 percent increase in lifespan. All animals in the study lived until they died of natural causes. The researchers used several tests to measure memory and learning. They found that growth-hormone-deficient rats had impaired learning ability compared to normal animals of the same age. A similar pattern occ...
