According to the World Economic Forum, human lifespan really does have a limit though self care is vital to healthy ageing. Research which looked at the “invariant rate of ageing” found that humans have a built in tendency to age.
And, whilst life expectancy has risen since the mid-1800s due to healthier, safer societies and although a lot of money has been spent on fighting ageing, we will not live forever because ageing is built into our genes. Scientists believe the “absolute limit” is 150 years but, one thing is clear, however long we live, self care is vital to healthy ageing. So, stick to a healthy diet, keep active, drink only in moderation, don’t smoke and you could live to be 150.
