Well, if this is some sort of a survey you are doing, in which the focus is on what weight distribution the population leans on, I think you would get very little data based on something so general. Age and Height are two factors that should be put along with this to get the best idea of what the weight distribution is. Just an opinion though, I don't know what your aim is. But anyway, I'm/was 170 when I last checked. Props to me from going to a 155 last year to 170!
