Exercise regularly, as it’s important for your health.
Take your walks, go on hikes, ride a bike, and work out with weights at home or at a gym.
Stretch out your body and stay flexible and youthful.
After a strenuous workout, it’s important to replace the fluids you’ve lost. Drink water before and after your workout, and during exercise if it’s appropriate.
Drink cool temperature water, and don’t depend on thirst to tell you; drink anyway!
