No part of our physiology exerts a bigger influence on how we think, feel, look, and behave than our hormones do. These chemical life assistants, secreted by glands distributed through the body — including the pituitary, the adrenals, the pancreas, and the testes — keep us in physiological balance. The energy to roll out of bed in the morning, the ability to repair and create new muscle after a teardown workout, and the wherewithal to rise to the occasion during sex are all orchestrated by hormones, nature's way of twisting the dials so we respond in the optimal fashion.
As we age, though, most hormones become erratic or go downhill, and in myriad ways, so do we. Thankfully, recent research has given us a more sophisticated understanding of how we can naturally pump the brakes on hormonal decline and, essentially, game the system. Consider this your guide.
