These days, you can order up a test to find out your biological age, an estimate of how quickly or slowly you’re aging compared to your peers. It’s based on an analysis of modifications in your DNA.
I took one of these biological age tests myself last fall at a longevity lab. The one I took is called GrimAge and it’s used by many longevity researchers to study aging.
After hearing my story about getting the test, listeners and readers wrote in asking how these tests work, how accurate they are and whether they should get one. Good questions!
