Nevertheless, a steep rise in death rates, as years advance into old age, is clear to see in all species," he added. For some, the news means one will never regain his or her youthfulness again.
In perspective, in the U. As The Guardian previously reported, the U. New research suggests that those who consumed more animal fat were 16 percent more likely to have a stroke than those who ate the least amount of animal fat.
In eight to 10 years, he expects to reach the promised land: a point where he can make a fully functioning liver that can be transplanted inside a body. But if a person has got a failing organ, does that indicate that perhaps they're coming to the end of a natural lifespan?
What if the heart and lungs also fail? One scientist estimates that millennials could live to Credit: Getty. His bet for how long we can live?

Watching her grow older, all while remaining sound, made Wang wonder about the secrets of ageing.
Most of it is bacteria, but it also contains fungi, viruses and other microbes, too. But we now know it has a profound effect on our body. Could our microbiome be the key to ageing? Credit: Getty. Recent studies show that our microbiome is as relevant to us as an additional organ might be.
It can influence how we behave and even how well we respond to different medications. She wanted to know whether our microbiome could affect ageing. Would the worm live longer? Three weeks later — by the time they should have all died — she checked on them. Some research suggests that tweaking our microbiome could keep us active longer in life Credit: Getty.
Older worms usually show a decline in physical activity, but the ones with the new microbiome not only wriggled around more quickly in their old age, but were less susceptible to disease too.
Wang is now carrying out tests on mice to see whether changing their microbiome extends their lives in a similar way. How long could that make us live? Something odd happens when you age. As cells gets older, they divide to replace cells that are dying or getting worn out, but this is not a perfect process. Senescence comes from the Latin word senescere — to grow old. But instead of dying, they hang around, acting in a destructive manner and communicating with cells around them.
That can cause a lot of trouble. As we age, more of our cells signal to other cells that they, too, should get older Credit: Getty.
