The question is: how do we quantify our biological age? The answer is in our aging biomarkers. Human life extension is fundamentally concerned with how old we are on a molecular level-and how quickly we are aging and, consequentially, how long we might live. I-like many other spanners-am far more concerned with biological aging (sometimes called phenotypic aging). The thing is, my chronological age, or how old I am based on the day I was born, isn’t something I have much control over. This is all to say that even our smartest computers can’t tell how old we are based on our looks alone.Īnd also to say that if I’m serious about anti-aging, I need to wear my hair down and more makeup if I’m going to make it to 80. Pulling my long hair up into a ponytail ages me by over a decade, and standing in natural lighting makes me appear younger than I actually am. The application then guesses how old the user is based on their uploaded face. Microsoft offers a free application called that uses machine learning to analyze an uploaded photo with a face on it. As a 31-year-old woman, that’s, ahem, less than ideal. When you buy using links on our site, we may earn commissions.Īccording to Microsoft, I’m either 46-years-old, 37-years-old, or 29-years-old.
