Well maybe not a fountain. Ocean is your friend Thoughts and observations as they say we came from the ocean in our beginning. Our tiers and blood are at the same salinity as the ocean . Very close to the same PH. There is every mineral ever known is floating around in the ocean. I found when I sailed for six years and was in the water every day I was never sick not even a cold. As I analyze what was happening I see that the blood runs at a very tight PH and if it goes a little acid it pulls calcium out of bones and teeth to re balance the level If you know PH if you have a acid and mix in an alkaline it changes and can not stay the same. They say cancer likes an acid environment. Sitting in the ocean would make your body more alkaline without any effort on your part. Second is your body ability of balancing minerals if you have a deficiency the body will pull it in and if you are toxic the body will get rid of it when you are sitting in a soup of all the mineral the body can pull in what it wants and push out what it does not. Some people pay for hot salt baths spays and the oceans are free. Also there is the stray electricity in the body grounds out through the sand and water. Probably a little extra bonus is vitamin D from the sun. Although I have no proof of this but I do think if you had a chronic problem laying on the beach in the water would help a lot.
