How old are YOU really? AI-powered tests reveal your biological age

New AI-powered tests tell consumers their biological age by determining the speed at which organs, cells and tissues decline. Startups are launching at-home tests that collect blood, urine or cheek swabs to analyze changes in the'epigenome,' the machinery that helps read the DNA code. Tally Health, one of these companies, recently presented 13 years of research showing that epigenetic changes can be safely reversed in mice to improve the function of tissues, akin to reinstalling cellular software. And the firm believes the same can be done with humans. Elysium also has a biological age test that provides'science-backed recommendations' to help consumers improve bodily functions, hoping to turn back time.
