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.
RE: When does morning, afternoon, evening and night begin? When does morning, afternoon, evening and night begin? So what are the times? You could say morning starts at 12.01am, but its still night, so do you class it as night? If so, when does the morning start?

Afternoon is after noon, 5pm becomes evening. The day starts when the SUN raises. Normally afternoon , evening, night commencements are understood based on this. Therefore when SUN raises at 6.00 a.m ., 12.00 clock is noon & then starts afternoon , evening therefore will be 6.00 p.m and 12.00 midnight. Evening is the time in between day and night. When the sun is leaving and the stars are entering.
