For me, it's talking to the doctor about my BMI (she says it's too high). \n\nOkay doc, I get it.But, I might not be as unhealthy as I think\u2014at least according to Oxford University mathematics professor Nick Trefethen. The numbers genius recently told The Economist that the decades-old BMI formula is flawed. His argument: The current formula is biased against tall people.\"We live in a three-dimensional world, yet the BMI is defined as weight divided by height squared,\" he wrote, adding that it's skewed to make shorter people think they're healthier than they really are.Trefethen also revised the formula to support his argument (you can calculate your BMI based on both formulas here). Does the new BMI formula really change that much? Not really. What really matters\u2014at least from a health perspective\u2014is body fat percentage.And from a personal perspective? If you're happy with your body and feel healthy, that's all that matters.Want more from Meagan? Follow her on Twitter."^^<http://www.w3.org/2001/XMLSchema#string>
