Answer:
Phantom pain.
Explanation:
Phantom limbs or phantom pain is a phenomenon where receptors in the brain pick up pain or movement from a nonexistent limb. For example, if you put your hand where someone's leg <em>would be</em>, they would be uncomfortable, as you'd be putting your hand through their phantom limb. Despite it not being their, your brain may still feel like it is. This is also seen in animals, as a cat or dog with an amputated back leg will try and scratch their ears or sides with a limb that isn't there.
Sociology that might be wrong thought , sorry
"Body composition assessment is a physical test that measures the proportion of the various components of a person's body. The human body is comprised of water, protein, fat, and minerals, but for most purposes, it is the level of fat compared to lean mass that is of interest. In general, most body composition analysis tests measure the ratio of fat to lean tissue. Body fat, or adipose tissue,
has chemical and physical properties that allow for a number of analytical methods, each with its own advantages and limitations."
