Upsurge in hormone ...

The sharp activation of the hormonal system is completely appropriate - when the parachute jumping jumper can be very useful, and increased reaction and acute mobilization of all forces. Of course, perhaps in reality the probability of PDE relatively small, but then the rate of - life. With the improvement of "technology" leap will occur and the confidence and awareness of a lesser degree of danger. Our "personal computer" - our consciousness - rationalize and optimize our emotional and stress reactions. If we are aware (or unconsciously aware of) our poor readiness to pounce, then the emotional stress response, we will be more pronounced (more intense). If we are absolutely confident in yourself, and stress reaction will be minimal. As the authors note in WWW.neurosoft.ru: "Properly staged training process allows to remove the pathogenic effects of stress." But spend a thought experiment: block any action paratrooper at the time of the jump, skuem his arms and legs so that he could not take any action, make any motion and threw him in a parachute "on the machine, providing him with The degree of safety not less than the usual jump. Although any preparation (stress) response in such a situation would be almost meaningless - in fact blocked any action, which prepares the preparatory reaction, and although the parachutist can be aware of the meaninglessness of your stress reactions, but of course, such a "way to leap" will not be an effective method in combating stress. Some level of stress reaction, and possibly even greater than at the usual jump in parachute course will be. But why? For clarity, slightly modify this thought experiment. Suppose the probability of risk is significant - for example every N-th parachute obviously does not work. The danger is real and significant for life. At the same time, "descent" is so locked in their actions, that the likelihood that he somehow sverhusiliem still destroy the lock, and if there is a risk, still help yourself is, say, ten to the minus tenth degree. (Ie, it is virtually zero, but from a mathematical point of view, zero-effectiveness in this case can not be, there is always some, albeit scanty, probability). In this case would act as a rational selective machine? If the omission is 100% death, the preparatory reaction would have been rational, even if her performance would have been, and ten to the minus tenth degree, and any other, even more miserable velechinoy. But if the danger of loss in case of inaction would not be 100% and 10% for example, the most rational selective machine began to calculate the selective benefits: 10% risk means a 10% chance of loss of existence, which is equivalent to losing 10% of those "selective glasses" who else could have scored for the rest of my life. In the case of preparations (stress) reaction, whose efficiency is 10 to the minus tenth degree, the equivalent loss would be equal to (approximately simplified!) = 9.9999999 etc.
