Just after Christmas, I went to put on a pair of jeans and discovered that they would no longer fit. I stood on the scale, and discovered that my weight had hit 88kg. My height is 1.84m. That means that according to the minimum risk curve, my optimum weight is 80kg. You might be aware of the fact that some studies suggest being slightly overweight leads to lower mortality. That’s true, but only across the entire male population; if you separate it into smokers and non-smokers, the non-smokers have a minimum mortality at a lower BMI, around 23-24.
