I agree wholeheartedly with your prescriptions in this video. And mentioning hoverboards reminds me of when the inventor Dean Kamen unveiled the Segway and hailed it as an invention that would revolutionize society such as the PC or telephone has. Someone commenting on the Segway once said it was, " just another way for us to be lazy". I couldn't agree more! Just walk...or get a bicycle. Both have fantastic health benefits.
