The idea that drinking eight glasses of water a day is good for your health has been dismissed as a myth.

Scientists say there is no evidence drinking large amounts of water is beneficial for the average healthy person, and do not even know how this widely held belief came about.

I can tell you exactly when the idea that everyone needed to drink 8 glasses of water a day started. It started when they started selling water in little 8 oz plastic bottles. Shortly after that started, everyone was made to believe, whether they are thirsty or not, they needed to have water on them all the time and be constantly consuming it.

Don’t believe me? Lewis Black agrees with my theory. Watch this video of him ranting about water, and be prepared to laugh your butt off.

Warning: Mr. Black does curse. If you are offended by adult language, you should get over it or not watch the video. It is so worth it though. Really funny stuff!
