Not so sure them dds is correct .And not a coincidence this thread is in August ,13th is left handed day due to one studies findings that may be incorrect but there is evidence it’s not random . Here Tran relies on a number of assumptions. The first is that testosterone levels increase in the presence of daylight, via vitamin D. This has been confirmed. The next is that a mother’s testosterone levels influence the levels of the fetus she’s carrying — also confirmed. Where the science breaks down is in the third step, where the hypothesis comes in. It says greater intrauterine testosterone levels cause a delay in maturation in the left side of the brain, which, if brain lateralization holds true, means a person’s right hand would become the non-dominant hand. Thus, a lefty is born.
