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. A camera that detects liars by monitoring the temperature of their face could lead to more acurate detection of terrorists and illegals at airports and border crossings.

up vote 1 down vote. The answer to this question will vary depending on the season, as the winter months have shorter days and the summer months have longer days. Furthermore, there is no standard set of times that are universally accepted That being said, here is my classification of times: 1  Morning is from sunrise to 11:59 AM. 2  Sunrise typically occurs around 6 AM. 3  Noon is at 12:00 PM. 4  Afternoon is from 12:01 PM to around 5:00 PM.
