Interesting how physical activity is not showing up in any of these so called experiments. Why is this trend to outsmart the body? Give it a bit of work and you'll have a balance and energy that no wii fit and alarm clock can asses. No gadget nor habit can outperform a few push-ups with an intense workout or an energetic soccer game. Your body will tell you when it's time to sleep and when it's time to eat and believe me it will correlate with your working day.

Mens sana in corpore sano.
