Oh those scientists, busy doing thier... sciency stuff.
Scientists have found that a primitive hunter gatherer at 30 would have had the same odds of dying as a 72-year-old in a developed country does now.
And over the course of 8,000 generations of humans, the biggest drop in mortality has occurred in the past four.
Since 1840, the life expectancy of a newborn baby in a Western industrialised nation has risen by around three months each year.
Lifespans are now beyond 80 in some developed nations, thanks to improved medicine and nutrition.
The Max Planck Institute for Demographic Research in Rostock, Germany, say that modern healthcare and medicines are responsible for increased life expectancies.
Researchers have studied the death rates of hunter-gatherers whose way of life has not changed for generations.
They looked at tribal people in Australia, Africa, South America and the Philippines and found that at 30-years-old, these people had the same chance of dying as Japanese people aged 72.
