Child gender by updating the blood
According to the theory, with a certain periodicity, rejuvenation of blood, tissues and mucous membranes occurs, as a result of which people become physically updated. This happens 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.
