Could humans live to 150?
Until the 1970s, it was generally agreed that 120 years was the maximum human lifespan. In 1995, this limit was pushed back when Jeanne Calment, a citizen of France, celebrated her 120th birthday. She died at age 122 and holds the world record for human longevity. But as our understanding of genetics and of ageing improves, it may become possible to slow down or halt certain biological processes. Today, scientists no longer dismiss the idea that humans might live for 150 years or more.
