Here is what the study said. Researchers admit that life expectancy has soared well past expectations, faster than it ever has in the past 200 millennia. According to a report on CNBC website:

“Published in the Proceedings of the National Academy of Sciences of the United States, the study looked at Swedish and Japanese men – two countries with the longest life expectancy today. It concluded that their counterparts in 1800 would have had lifespans closer to those of the earliest hunter-gatherer humans than they would to adult men in both countries today.”

Basically, those primitive hunter gatherers, at age 30, had the same odds of dying as a modern Swedish or Japanese man would face at 72. Just how that affects our ultimate life expectancy is anyone’s guess. But the important point is that scientists are finding that life expectancy is much more controllable than ever imagined.
