How much should a 37-year-old weigh?

There is no specific weight for a 37-year-old (or a person of any age) because weight is related to height and body composition rather than age. Please feel free to ask the question again and include more detail. In any event, body weight is a misleading measure. What counts more than your body weight is your body fat percentage.
