Hi, my name max. I wanna use hydrogen breathing device, just because I think it will help for my body much. So I would ask some questions about it. If it's so good as many resources tell why not many hospitals and also people use it for their health? And also, how hydrogen works with body I already red but how about brain, will it cause some damage by getting only hydrogen. If you don't know, can you just recommend resources where I could find this information, thank you much.
