脑科学研究证明:人的大脑对身体的控制是交叉的。左半球支配右侧肢体,右半球支配左侧肢体。人出生时,大脑两半球有相同的生理特点,其生理功能也相同。但是,它们在一个正常的成人身上却有着巨大的差异,这一差异完全来自于不同“训练”的结果。平常,多数人总习惯使用右手和左脑。因而在步入中年之后,左半身器官的的衰退比右半身更明显。如头部左侧白发增多,左眼老花远视,左耳听力下降,左侧肢体乏力,甚至记忆力衰退,正常用脑的持续力和效能下降,而左手和右脑的功能也得不到应有的锻炼和提 Brain science studies have shown that human brain control of the body is cross-cutting. The left hemisphere dominates the right limb and the right hemisphere dominates the left limb. When a person is born, the two hemispheres of the brain have the same physiological characteristics and their physiological functions are the same. However, there is a huge difference between them in a normal adult. The difference is entirely the result of different “training”. Normally, most people are used to the right hand and left brain. So after entering middle age, the recession of the left half of the body is more obvious than the right half. Such as increased white hair on the left side of the head, presbyopia on the left eye, decreased hearing on the left ear, weakness on the left limb, and even memory loss, the sustainability and efficacy of the normal brain are decreased while the left and right brain functions are not obtained Due to exercise and mention
