A team of researchers from universities in the United States wanted to figure out the role of genetics in human lifespan, specifically relating to growth hormone. The researchers’ work shows two main things: First, that a mutation in men’s DNA relating to growth hormone might lead to a longer lifespan. And secondly, that treating older people with growth hormone might be dangerous if they don’t have the variation.
