Change your brain

Scientists are discovering the brain is incredibly malleable, and that we have the power to change it for the better. Naturally, exercise and diet are two ways of rewiring it through a process called neuroplasticity—when the brain remolds itself. But so do stimulants such as coffee (it can improve short-term memory), video games (they boost mental dexterity), music (it reduces fear) and meditation (which can inhibit anxiety, high blood pressure and even some skin disorders).
