So, in other words, if you get a biological test at the age of 50 that says you are 25, before you give yourself high fives, ask yourself the following question. Does that really mean that you're going to live another 55 years, which is what you would expect if you're 25 years old? And I think the answer is no. If you're chronological age is 50 and you get this test, I don't think it means you're going to live to be 105.
