Many people blush when they are telling a lie. It's a very subtle phenomenon but this slight increase of blood flow to the cheeks can be detected.

It would also be confusing to change the clocks at midnight back to 11 p.m., because that would change not only the time, but also the day, Live Science reported. Once daylight saving (not savings, as many people say) time ends, most Americans will stay on standard time until March 12, 2017.
