I am concerned about the emphasis on drinking large quantities of water. Please research hyponatremia. It appears that our society has been over focusing on drinking water and it has become quite dangerous. I listened to a podcast recently that discussed this and we should just all be aware of the very real dangers of consuming too much water during the day.
Google hyponatremia. Or athletes dying from drinking too much water.
I know that many of our challenges are pushing water consumption and we might be encouraging something dangerous.
