Do you ever need a quick refresh to just kind of wake yourself up? Next time you need to feel a little refreshed, try this. Get some water on your hands and then with your wet hands, touch the inside of your elbows and knees, and then the back of your elbows and knees. Your elbows and knees are devoid of oil glands and quickly become dry. That is the reason why your elbows and knees are darker than the rest of you. Also all of the nerves in your arms and legs travel across the elbows and knees, making them very sensitive. So the next time you need a quick pick me up, try the water on the elbow and knee trick 🙂
