I used to make fun of the tinfoil hat people, but I'm not laughing now. There's so much EMF in our environment now that it's ridiculous, and I found out that aluminum foil does in fact do a decent job of blocking it out. Those guys may have been onto something. They were pioneers, ahead of their time (since back then there was relatively little EMF). Now the stuff is everywhere ... not only their cell towers, their 5G, cordless phones, WiFi networks, satellites beaming 1000s of channels all over the earth, dozens of radio stations whose signal you can pick up everywhere, smart meters for utilities, etc. This stuff is bombarding our environment.
