People born in 2030 will have longer lives than scientists once thought possible, but American babies born in 2030 will continue to have one of the lowest life expectancies of any developed country, according to a new study.
Scientists once thought an average life expectancy beyond 90 was impossible but medical advances combined with improved social programs are continuing to break barriers, including in countries where many people already live well into old age, according to the study's lead researcher, Majid Ezzati of Imperial College London.
"I can imagine that there is a limit," he said, "but we are still very far from it."
Ezzati estimated that someday people could survive on average to at least 110 or 120 years.
The study shows South Korean girls born in 2030 are likely to have the greatest lifespan. They'll have a more than 50 percent chance of living past 90 --that's roughly 7 years longer than South Korean girls born in 2010. The longevity of South Korean women estimated in 2030 is due largely to investments in universal health care, he said. South Korea also led the list for men.
