Human life expectancy in high-income countries is no longer climbing at the rate it did in the 20th century, a new study suggests.

A new study found that increases in life expectancy have slowed over the last few years, reaching a plateau. Here's how to increase yours, according to doctors.

Human life expectancy has just about peaked, according to a study published Monday in the journal Nature Aging, and barring a transformative breakthrough in medical science, people will top out at a maximum average age of around 87 — 90 for women,
