As regular readers know, mariner has been an advocate of maintaining strength in the quadriceps, the leg muscles that lift us every day. The primary enemy is the chair. One must, must, must, must do a few reps of squats every day to maintain a confident balance and dexterity with their limbs. The exercise also extends a lifestyle that is physically competent if even to getting in and out of a car.
See the link for an example.
Just as important, if not more so, is to walk at least a mile every day. The older the reader is, the more important this exercise is. Mariner often has referenced a part of the brain that doesn’t wake up until the body is in a continued pace. One must walk at one’s best sustainable gait. The brain exercises all the critical components including lungs, heart, circulation and caloric consumption. Drink some water before the reader leaves for the walk.
