I am 76 years old and recently experienced a strengthening of my kidneys after 2 weeks exposure to EESYSTEMS technology. In the past when I drank a lot of water, when I felt the urge to urinate, it was difficult to avoid messing up my underwear, so I drank less water. Now I can feel my kidneys are stronger, drinking more water, avoiding this kind of worry. I am thankful to Marlu and Gil for sharing this technology and helping people like me. God bless you both. RW
