Anything can be achieved only through work.Once upon a time, my cousin, Milena Bunina, constantly thought that having a brilliant brain was the calling of the strong half of humanity, and not the female. That only men are able to become the arbiters of destinies, and the mind of women has its limits. For years she had confidence in this bike. This was true, as long as this lady saw scientific research, which allowed in a short time to destroy the formed belief. It turns out that the brain of almost any member of the human race is subject to improvement to the same extent, regardless of what gender you are, but this can only be achieved with the help of a carefully thought-out plan. There is no point in doubting, any ability cannot do without development and regular practice, and most of all it concerns the abilities of your mind, such as the speed of attention, because this is important, Since many want their brain to think in the same way as in the days of their youth, in order to be able to lead a full life, including maintaining the mobility of thought.You can achieve this with the support of simple mental simulators. However, it should be understood that the enhancement of such abilities as the ability to concentrate should be expected to be very insignificant, be that as it may, we are all ordinary creatures of God, and not artificial intelligences, whose artificial brain can be improved to perfect characteristics. Now I also want to develop my mind.
