The idea of a fish being able to produce electricity strong enough to light lamp bulbs—or even to run a small electric motor—is almost unbelievable, but several kinds of fish are able to do this. Even more strangely, this curious power has been acquired in different ways by fish belonging to very different families. Perhaps the most known are the electric rays, or torpedoes, of which several kinds live in warm seas. They possess on each side of the head, behind the eyes, a large organ consisting of a number of hexagonal-shaped cells rather like a honeycomb. The cells are filled with a jelly-like substance, and contain a series of fiat electric plates. One side, the negative side, of each plate, is supplied with very fine nerves, connected with a main nerve coming form a special part of the brain. Current gets through from the upper, positive side of the organ downward to the negative, lower side. Generally it is necessary to touch the fish in two places, completing the circuit, in order to receive a shock. The strength of this shock depends on the size of fish, but newly-born ones only about 5 centimeters across can be made to light the bulb of a pocket flashlight for a few moments, while a fully grown torpedo gives a shock capable of knocking a man down, and, if suitable wires are connected, will operate a small electric motor for several minutes. Another famous example is the electric eel. This fish gives an even more powerful shock. The system is different from that of the torpedo in that the electric plates run longitudinally and are supplied with nerves from the spinal cord. Consequently, the current passes along the fish from head to tail. The electric organs of these fish are really altered muscles and like all muscles are apt to tire, so they are not able to generate electricity for very long. People in some parts of South America who value the electric eel as food, take advantage of this fact by driving horses into the water against which the fish discharge their electricity. The homes are less affected than a man would be, and when the electric eels have exhausted themselves, they can be caught without danger. The electric catfish of the Nile and of other African fresh waters has a different system again by which current passes over the whole body from the tail to the head. The shock given by this arrangement is not so strong as the other two, but is none the less unpleasant. The electric catfish is a slow, lazy fish, fond of gloomy places and grows to about 1 metre long; it is eaten by the Arabs in some areas. The power of producing electricity may serve these fish both for defence and attack. If a large enemy attacks, the shock will drive it away; but it appears that the catfish and the electric eel use their current most often against smaller fish, stunning them so that they can easily be overpowered. Why are horses used to catch the electric eels

Thinner isn"t always better. A number of studies have 1 that normal-weight people are in fact at higher risk of some diseases compared to those who are overweight. And there are health conditions for which being overweight is actually 2 . For example, heavier women are less likely to develop calcium deficiency than thin women. 3 , among the elderly, being somewhat overweight is often an 4 of good health.Of even greater 5 is the fact that obesity turns out to be very difficult to define. It is often 6 body mass index, or BMI. BMI 7 bodymass divided by the square of height. An adult with a BMI of 18 to 25 is often considered to be normal weight. Between 25 to 30 is overweight. And over 30 is considered obese. Obesity, 8 can be divided into moderately obese, severely obese, and very severely obese.While such numerical standards seem 9 , they are not. Obesity is probably less a matter of weight than body fat. Some people with a high BMI are in fact extremely fit, 10 others with a low BMI may be in poor 11 . For example, many collegiate and professional football players are 12 as obese, though their percentage body fat is low. Conversely, someone with a small frame may have high body fat but a 13 BMI.Today, we have a(n) 14 to label obesity as a disgrace. The overweight are sometimes 15 in the media with their faces covered. Stereotypes 16 with obesity include laziness, lack of will power, and lower prospects for success. Teachers, employers, and health professionals have been shown to biases against the obese. 17 very young children tend to look down on the overweight, and teasing about body build has long been a problem in schools.Negative attitudes toward obesity, 18 in health concerns have stimulated a number of anti-obesity 19 . My own hospital system has banned sugary drinks from its facilities. Many employers have instituted weight loss and fitness initiatives. Michelle Obama has launched a high-visibility campaign 20 childhood obesity, even claiming that it represents our greatest national security threat!
