Sweat

While I was working out yesterday I noticed that the sweat would gather itself into drops and fall off of my body once they got to heavy.  I had always wondered why it didn't just slide down my body without forming into drops.  I thought about it for a while using what I have learned and I think that I have found the answer to my question.  The way sweat works is really quite amazing to me.  The water it self is like an insulator that takes away heat and keeps me cool once I have gotten to hot.  It does this using its specific heat quality.  This wouldn't work if the water just slid off your body like gravity wanted it to.  The water molecules us cohesion to stick together and make a layer on your body and it uses adhesion to stick to the body.  Because of these qualities water is perfect for controlling body heat.  Staying cool lets your body work longer and for that we thank sweat and the properties of water.  I used to get mad that I would sweat so much but now that I know what it does I'm glad it does it.
