Young adults often live like they are invincible, and most are outwardly pretty healthy. But we already know enough for all of us to take biological aging seriously and to try to do something about it while the scientists keep working on better braking systems. We aren’t there yet, he and other researchers say. Austad, a distinguished professor and biology department chair at the University of Alabama at Birmingham. They don’t expect to cure aging, “but what we’d like to do is change the rate at which that happens so that, in 20 years, you might age 10 years,” says Steven N. They also are working on ways to slow it down with drugs, dietary regimens, and other approaches. Researchers are developing new ways to measure it. In 2020, biological age is more than just a feeling-it’s a science. Fast biological aging is what we fear when we say stress has taken years off our lives. Slow biological aging is what we perceive in a friend who looks younger than her chronological age.
