Formula to determine the physical age of fats based on BMI To start with, this is obviously not a real formula.  This is an idea I came up with while replying to another post. I think we should create some sort of mathematical formula to determine someone's physical age by how fat they are.  This will let us determine roughly hold old their bodies are (compared to someone who hasn't destroyed it by eating like a pig) and when they're going to die. All mathematical shitlords should try to create the best one they can.  This is my current formula, meant to be applied ONLY to people with a BMI of 25 or greater.  (Excluding bodybuilders.) Age * ln (BMI - 22) So if a 20 year old had a BMI of 35, we'd get: 20 * ln (35 - 22) = 51 Therefore, this fatass has a body of a 51-yr-old.  By the age of 30, they would have the body of a 77 year old.  You get the idea.  The formula is still flawed, but I just know that there's a math-happy shitlord out there that can come up with something better.
