Did you know?
Did you know... ... that in addition to being Martin Luther King Day, January 18 is also the birthday of the Polygraph? In 1951, the first lie detector test using a polygraph took place in the Netherlands. Trivia buffs: A polygraph measures and records blood pressure, pulse, respiration, breathing rhythms, body temperature and skin conductivity.

I've seen where they are working on a polygraph machine that scans the brain waves. It may be able to provide even more reliable results.
