dominant hands

Did you know that only one in 10 people is left-handed? Although it is curious that the number of right-handers is much higher, the real mystery is why the vast majority of human beings have so much more motor skills with one hand or foot. According to researchers, this can happen due to the fact that the choice for one side is the result of more intricate wiring in the side of the brain that involves speech (which also requires skills motor).

However, this theory may have a problem, as some right-handed people control speech with their left side, while others are left-handed with their right.

Breasts
