I’ve had my bedroom upstairs for most of my life. To counteract any un-grounding, I regularly crash my bike into the Earth.
Seriously, there have been some wack-a-doodle journal articles lately that have somehow made it through peer review (usually dubiously credentialed peers). We’re calling it an Info-demic, since it seems to have manifested into a problem during COVID-19.
I’m pretty sure grounding is rubbish.
