Wait, how old are you? The lowdown on genetic testing and your biological age
With genetic testing, the question “How old are you?” is taking on new meaning. Rani Sheen finds out her biological age.
I’m staring at a password-protected PDF file that has arrived by email, thinking, “What if I’m a 30-something in a sexagenarian’s body?” I have the password, but I’m hesitating because the information within is potentially significant: It will tell me my “biological age,” as opposed to my chronological age, giving an idea of how fast my body is aging. The results of a blood test I submitted to at Sha Wellness Clinic in Spain three months earlier, this number was arrived at by measuring my telomeres—which sit on the ends of every chromosome like a protective cap, guarding the crucial genetic information inside—and comparing the results to a database of other test subjects. Although I don’t have any major health complaints, generally feel pretty good and, at 34, don’t go to the liquor store without ID for fear of refusal, I can’t help but imagine finding out that my body is speeding toward dicky knees, 5 p.m. dinners and walkers before its time.
