Percent. Ie, put simply, the action of the preparatory response (ie stress) in a situation such that an equivalent block lower selective loss of ~ one trillionth of interest. While approximately one-trillionth translate this into real life - maybe it can not compare more than 1grammom food, or even with a much smaller volume. At the same time, the loss of resources for preparatory responses may be significantly and many times higher. Losses from irrationally spent on stress reaction of the resource may be even many times more important if the preservation and best use of resources in the future will depend on the effectiveness of action in critical situations. Maximally rational selective machine, having considered mathematically selective loss probability and the probability a selective advantage, in general, "cut off" would be a preparatory response (stress), if it were able to respond to the action would have been very low (ie, blocked). This is the most cost-effective strategy, and such a strategy would be to elect a man in a similar situation. Such criticism is significant hazardous situations in which the stress response is totally unnecessary, irrational, almost meaningless, may occur quite frequently. It is not only non-standard, emergency situations "isolated sites" - underwater and surface merchant ships, airplanes, etc., when the majority of team members (or even the whole team), requires no heightened preparations (stress) response, and high-normal performance of their functions. Different people have the notion of significant risk to life in different situations may be entirely different. For someone and jump from the tower into the swimming pool can be perceived as a significant threat to life. Maximally rational selective car in such situations, having considered all the options, in general, "off" in their reaction to stress. In any critical situation, if the stress response was not rational, it would be totally "cold blood". As I said earlier, this same strategy would be most beneficial to humans. But can a man so to optimize your emotional stress response, and if he can, how, and if he can not, why not? For effective selective machines only and most important criterion is the selective advantage, set the maximum number of "selective points." But the body is a "living system", ie In this case, a person not originally formed the process of evolution, as a counter to gaining "selective points." Maximizing the selective advantage is not achieved by counting the "selective points." Nature has endowed the organism "pushers" that move, cause the organism to the most appropriate action. The desire to eat, sleep, move, or relax, to have children, to avoid pain - all these and many other "pushers" - instincts (drives, unitary instincts of the program - in this case it does not matter), induce the body to selectively most appropriate action.
