Aging Happens in Bursts (new study!)

This might explain a few things.


A new study tracking 108 Californians between the ages of 25 and 75 found that human aging is not linear! Instead, they found bursts of disruption in molecular markers of aging at 2 points in time:


▪️ Around the age of 44, changes occur that affect the metabolism of lipids, caffeine, and alcohol

▪️ Around the age of 60, changes occur that affect immune function, kidney function, and the metabolism of carbohydrates


The study used the words “waves” and “crests” to describe the moments across the lifespan when aging activities spike. At both the age 44 and age 60 crests, muscle and skin aging also accelerated.


Do you think your body has hit one of these aging bursts?
