Every single human being on this planet has the need to lay down at night and sleep.  Young, old or in between we all love to catch some zzzz's at the end of a long day.  If you think about it, it is pretty strange.  We get undressed and put on some jammies (some prefer to go commando) and then we get onto a big soft pad wrapped up like a burrito.  Then we just lay there for 8 hours or more while our heads play movies for us (dreams...).  We do this every single day!  Or hopefully anyway... So why do we even need to sleep in the first place?  To start off, if we don't sleep, we will literally go crazy.  It will induce psychosis and in fact will eventually kill you.  So yes, you have to sleep or you will die...  However, no one really knows exactly why we need sleep.  There are many theories, but this is still a widely studied topic in the science community. Some theories of why we need sleep: Sleep allows the brain organiz...

When we get sad, hurt, or when we laugh too hard, for some reason our eyes start leaking water (or saline)...  That is pretty freaking weird if you really think about it!  Why does the body have a need to cry for feeling sad or hurt? Women cry an average of 50 times a year and men cry and average of 10 times a year. The body actually has 3 kinds of tears: basal, reflex and psychic. Basal Tears:  Keep your cornea (the transparent front of your eye) nourished and lubricated so your eyes don’t dry out. Reflex Tears:  Help you to wash out any irritations to your eyes from foreign particles or vapors Psychic Tears: Tears produced in response to that strong emotion you may have from stress, pleasure, anger, sadness, laughing, and physical pain All these different types of tears even look different under a microscope!  They are made up of different kinds of molecules.  I can understand the tears to keep eyes moist or to flush out a foreign object,...

There are many things in life that if you really think about it are pretty weird and strange...  Take for example clapping hands to show approval.  Where did this social norm even come from?  Someone does something we like and we slap our hands together like goofy seals. Pretty freaking strange! So where/when did this behavior start?  Well, no one really knows.  It goes far back to the Romans who would snap fingers, stomp feet and clap hands.  Other cultures and old Christian churches waived linens to show applause.  So where the heck did clapping come from and why do so many cultures around the world do it? One interesting thing is that babies start at a young age to do this to show excitement.  Did they learn it from the parents or is it just inherent?  Many animals clap when excited.  Some theories suggest it stems from early humanity when they would sit around a fire and clap rhythms.  Perhaps it started there....
