"Wow, some of the members of CureZone are suspicious to the point of paranoia!"
You can call it paranoia if you want, I think that everybody who reads this forum should take all information with a grain of salt until it can be verified. You didn't allow for this, and my searches didn't come up with anything that would verify the information you posted.
To my mind, anything worth posting on this forum is worth a link, or reference to a source for verification. Everything else only qualifies as an opinion, and you heard about Opinions I'm sure. Opinions are like A-Holes, everybody has one.
It is not my intention to get sideways with you, only to verify what is important information to me. I do have an FIR (Far-Infrared-Sauna) sauna, and if it is dangerous, I want to know about it. I'm sure you can understand this.
