I am posting this because many people struggle with loneliness, especially during the holidays. So if you are attending singles events or have signed up for online dating, you'll definitely want to read this post in great detail.
One of the first things I was taught in face reading (a part of my body language training when I was a teenager), was "beware of the eye whites". In other words, if you can see the whites of the eyes (called sclera) under the colored part (iris), these people can be very cruel, calculating and dangerously violent. After working in jails and prisons as an officer and then a Forensic Mental Health Professional (FMHP), I could see a very strong correlation of the types of crimes they were being accused and / or convicted of.
Alongside the "eye whites", was the next lesson... "beware of the down-turned mouth" for much the same reason - especially in those under 40 years old. After that age, sagging skin and gravity act together and automatically pull the corners of the mouth downward. Perhaps this picture of mugshots will clarify. I only noticed that those with this type of mouth are more pessimistic and prone to depression. For me, the eyes took the prize!
Below are just a few of the serial killers & animal abusers with the "eye white warnings". Don't take my word for it, do your own online search for killers, murders, burglars, child molesters, etc. and see how many have these eyes (and even mouths).
Oh, and if you're dating, well...

Disclaimer: as with anything else, this is not 100% across the board for everyone but the results during my 35+ year forensic career were startling enough to warrant this blog post.
