Everyone should have SOME sort of a scale like this Nokia Body Cardio scale. A scale which lets you see those composition numbers. It's critically important for a person not just to know their overall body weight but also the percentage of fat, muscle, and water they are. A person who is 160 pounds and mostly muscle is quite different, health-wise, from someone who is 160 pounds and mostly fat. It's important to know that difference. A scale like this sends a mild electrical signal up through your bare feet and can tell your composition based on the way the signals return to the source. The science is well proven.
