Any Video with David Icke immediately sends alarm bells ringing with me, he has made an absolute fortune spreading some absurd stories (have a read of his "The Reptilian Elite" theory).
Ignoring the debate about the health risks around 5G mentioned in the first video, for me, there's a simple solution, switch off from social media, it's like a disease with no cure, I see people walking around in the morning on the way to work with their eyes transfixed on their phones blissfully unaware of what's going on in the real world.
