Energy level of Kids

I think if we actually went out and 'played' more we would have more energy. Many of the things we spend time on during the day and night are very mentally, put not physically straining. Ie. sitting at a computer reading, typing emails..etc. Your physical body is not doing much but your arms and fingers moving, therefore the longer you sit, the more tired you get. Instead of spending one night on the computer, play with your kids, or a dog...or do a board game...something that is away from the glow of the computer screen, tv screen, or phone. You will be amazed at how well you sleep that night, and how much energy you actually have in you.
