Calculator of child gender by the method of “Blood Updates”

According to the theory, with a certain periodicity, rejuvenation of blood, tissues and mucous membranes happens, as a result of which people become physically updated. This occurs all the time while a person lives. The period after which renewal takes place is different for both sexes: for the strong half of humanity – after 4 years, for beautiful ladies – after 3.


These data are the basis for the assumption that it is possible to find out the sex of the child by updating the blood.
