A group of frogs was playing in a shallow pond of water jumping from one stone to another.
A colorful fish, swimming by stopped and asked one of the frogs, “How can you jump from one stone and land exactly on the other?”
“It involves a little calculation,” replied the frog not paying much attention to the fish.
“Like what?” insisted the little fish.
“Well, I estimate the distance between the two stones, calculate the angle and velocity of launch to attain the necessary trajectory, make correction for wind speed, then flex the muscles of my rear legs the right amount and then release them to project myself towards the target. It doesn’t take a second,” the frog was more forthcoming this time.
“But you also move your front legs and also maneuver in the air,” the fish chimed taking pride in its power of observation.
“Aha,” retorted the frog, “the front legs assist in getting the correct angle and the maneuvers in the air are in-flight course correction. Can I go now?”
“How interesting, you can do all that without radar or computer,” sighed the fish and swam away curling its body from side to side.
“Silly fish,” chuckled the frog and went back to his leaping.

The Fish and the Frog
IRRITATION
Irritation plays a very important role in determining how an individual behaves in a given situation. A person behaves quite differently in familiar circumstances if he is suffering from a running nose or a toothache, there being a divergence between the two specific cases. Many people would avoid going to their place of work in these conditions not because they are afraid of spreading the virus, but because their changed behavior could alarm others. Irritation may be internal or external. Internal irritation usually takes the form of a pain or itching or secretion or occasionally an involuntary movement of a limb. External irritation adversely affects one of the senses, such as flickering light, an unpleasant sound or smell, dust, temperature or the movement of an object. To someone suffering from an internal irritation or a psychological condition, the addition of an external irritant can be quite disastrous. Even a normal and healthy person's thoughts can be decisively affected by an external irritation. Considerable research has been carried out on the effects of various irritating agents on the performance and efficiency of industrial workers. Fortunately human beings are endowed to a varying degree with an ability to manipulate their sensitivity to these irritating agents depending on their circumstances. Moreover, in all civilized societies there has been an organized effort to combat and reduce the sources of irritation. In most cases the effort has consisted of the implementation of sanitation and hygiene to contain the spread of irritating germs and gases. Landscaping helps to prevent dust, and lately air conditioning is becoming popular for controlling the temperature and humidity of enclosed environments.

PLEASURE AND PAIN
Almost all memorable human perceptions can be classified as either pleasant or unpleasant. When unpleasantness reaches a certain degree, we call it pain, and then of course there are degrees of pain itself. This work does not aim at discussing the mechanism of generation of particular impulses by the sensory organs in the nervous system which are identified by the brain as pleasure or pain. Nor shall we delve into the physiological aspects of the storage of this information in the brain cells. It suffices for our purposes that a feeling of pleasure is registered in the brain when sensory perceptions indicate things to be going right, whereas pain is identified when the sequence or nature or intensity of perceptions shows that something is going wrong. In this way pain is also related to fear which also has a series of consequential features, such as increase in the rate of heartbeat, seizure of digestive functions, sweating, dilation of pupils, redirection of blood supply etc. However, similar reactions are also observed in the case of anger or excitement as well as fear caused by reading or hearing an alarming statement involving complex analytical functions.
