No! I believe that was a technique used called Phreology (SP). It was used in the late 1800s to try to determine if a person was more prone to criminal activity. Mr Bill

Nope.

yeah maybe a fat person would rob the cake shop

There were a lot of theories back in the day that were related to this. The main one was physiognomy. It pretty much broke it down into three types the Ectomorph, the Mesomorph, the Endomorph. **After request for more information** The ECTOMORPH * Definitive "Hard Gainer" * Delicate Built Body * Flat Chest * Fragile * Lean * Lightly Muscled * Small Shouldered * Takes Longer to Gain Muscle * Thin The extreme ectomorph physique is a fragile and delicate one. The bones are light, joints are small and muscles are slight. The limbs are relatively long in proportion and the shoulders droop. The ectomorph is a linear physique. Straight up and straight down, and may appear longer than he or she really is, due to the length of limbs coupled with lack of muscle mass developed on those limbs. The ectomorph is not naturally powerful and will have to work hard for every ounce of muscle and every bit of strength he or she can gain. Other Ectomorph Traits The extreme ectomorph may have long fingers, toes and neck are long. A pencil neck you could say. The features of the face are sharp, and the shape of the face is triangular. The lower jaw is somewhat receding. The skin tends to burn easily. Extreme ectomorphs may suffer from extremes of temperature. Due to the great body area in relation to muscle mass, the ectomorph may suffer from great heat, and due to low body fat, the ectomorph may suffer from great cold. The hair is fine and grows quickly and is sometimes difficult to keep in place. The MESOMORPH * Athletic * Hard Body * Hourglass Shaped (Female) * Rectangular Shaped (Male) * Mature Muscle Mass * Muscular Body * Excellent Posture * Gains Muscle Easily * Gains Fat More Easily Than Ectomorphs * Thick Skin The mesomorph has well-defined muscles and large bones. The torso tapers to a relatively narrow and low waist. The bones and muscles of the head are prominent. Features of the face are clearly defined, such as cheek bones and a square, heavy jaw. The face is long and broad, and is cubicle in shape. Arms and legs are developed and even the digits of the hand are muscled. Other Traits of the Mesomorph The skin of the mesomorph is thick and the mesomorph tans well. The hair is heavy in texture. Endomorph * Soft Body * Underdeveloped Muscles * Round Physique * Weight Loss is Difficult * Gains Muscle Easily Like the Mesomorph. The body of the extreme endomorph is round and soft. The physique presents the illusion that much of the mass has been concentrated in the abdominal area. This may or may not be true. The arms and legs of the extreme endomorph are short in length and taper. This may give the appearance of stalkiness. The hands and feet of the endomorph are comparatively small, and the upper arms and thighs are often more developed than the lower parts of the arms or legs. The body has a high waist. Other Traits of the Endomoprh The skin is soft and smooth, and the hair is fine. The head of the endomorph is spherical. The head is large and the face broad. There are also combination types.
