Dis 6

  Water is everywhere.  We are composed of 60-70% water.  The earth's surface is about 71% water (https://water.usgs.gov/edu/earthhowmuch.html). Every day our bodies lose water and we must replace it (Lecture 7). Most of us are fortunate enough to have access to running water.  Why is drinking water such big business these days?  Choose one of the following topics to kick off your main post:

• Water requirements: The risks of dehydration vs. water intoxication 
• Vitamin Water - is there any benefit and are there potential risks?
• Alkaline Water - a trend these days.  Is this really beneficial?
• Electrolyte water such as Gatorade
• Which is better - tap water or bottled water
