My friend, an 84 yr old , had histoplasmosis as a child along with his two brothers. John’s Hopkins sent them home to die. The oldest and sickest asked to go to the river one last time so they took him. His fever broke and he improved and they put all three boys in the river and they survived and thrived through good long lives. Water, sunlight, trees, strong faith and supportive family.
