In this video, Dr. Angel Gracia first talks about the study published by Jed Fuhrman in Nature Magazine on June 10th 1999 with title "Marine viruses and their biogeochemical and echological effects." There the "marine soup" is described with its DNA, RNA, 10 billion viruses, and 9 billion bacterias per liter of seawater. https://www.nature.com/articles/21119
He also say how he arrived to be 90 years old, doing exercise by the beach, and living with nature. All for free. 99% of Doctors are looking for money. They don't have the time to practice and prescribe how to be healthy.
Seawater is recommended because it has all the [natural] elements of the periodic table, and DNA from the origins of life. Because life originated from the sea. And now we have the same DNA from the precambrian era 3.8 billion years ago.
In his books, Dr. Gracia backs mention several Nobel Laureates like Otto Warburg (1931) who said that all illnesses are acid. And if you have an alkaline body with plenty of oxigen (which you can get for free doing aerobic excercises) you can be as lively as him.
He also mention his course in Spanish with 300 graphics at https://wp.me/P8bbcJ-s
When asked if one glass of seawater a day is enough, he said that you need to learn how to drink it, which is written in his books and course.

Taking into consideration that the food pyramid recommends 2 liters of water, and that it is proven that our internal liquids are isotonic seawater, many doctors recommend drinking those 2 liters of isotonic seawater a day.
For my family I prepare isotonic seawater mixing 1 part of seawater with 3 parts of plain water. The amount in the graphic above is good for 1 person to drink during 2 days.
Nowadays you can find Dr. Angel Gracia doing his excercises by himself in West Palm Beach, Florida. But a decade ago he was teaching his dry swimming in Spain, as showin in the following video...
Be healthy.
