The world needs a “longevity-oriented” dating app, it seems 
Kayla Barnes, a 33-year-old wellness CEO based in Cleveland, was eager to pick up her date from the airport one spring evening last year. It would be the first time she would meet Warren Lentz, who lived in Los Angeles, in person, and the next step in a month-long burgeoning relationship that included countless FaceTimes, texts—and, most notably, a detailed exchange of personal health information.
After meeting Warren on Raya, a private, membership-based dating app, and before their first date, Kayla requested his health labs—including a gut health test and a total toxin test, measuring levels of heavy metals and environmental toxins in the body, plus a slew of other assessments, of nutrient levels, inflammation, and a range of biomarkers. Warren dutifully had them all performed by a local California clinic without hesitance. And Kayla knew, however unromantic, that both his compliance and his results would show more than any other dating compatibility test or ordinary deal-breaker question ever could.
