I do this a lot. I work from home, and yes I know I should sit at a desk like normal people, but I don't. I lie down a lot, and find the bump a convenient resting place for my laptop.
I'm not overly paranoid, and my partner is anything but, he hates anything woo or superstitious. But he tells me I shouldn't do this, that it's emitting microwaves, and him being a techie (a cynical one at that) I tend to believe him.
What are your opinions? Anyone else do this? Or is he just being an silly old worrywort?
