How Previous Am I, Actually? These Exams Measured My Organic Age

How previous am I, actually? I spat in a tube, swabbed the within of my cheek and pricked my finger to seek out out. 

I mailed my samples to 3 firms that promised to inform me my “organic age” based mostly on chemical modifications of my DNA. The outcomes, the businesses stated, can be based mostly not on after I was born, however on how a lot my cells and organs had aged.
