The progress of a human being through life might be thought of as a mostly gradual succession of changes from the ovum to the grave.
But if you wake up one morning, look in the mirror, and wonder when you suddenly grew so much older, you may not be imagining things.
According to new research into the molecular changes associated with aging, humans experience two drastic lurches forward, one at the average age of 44 and the other at the average age of 60.
“We’re not just changing gradually over time; there are some really dramatic changes,” says geneticist Michael Snyder of Stanford University, senior author of the study.
“It turns out the mid-40s is a time of dramatic change, as is the early 60s. And that’s true no matter what class of molecules you look at.”
