Thank you for that information, barryem, that stirs things in my memory which I've seen in documentaries. Correct me if I'm wrong, but didn't doctors, probably working from a remit from the tobacco companies, constantly repeat the "no evidence" claim until something like the 1980s?

Who funded the above-linked studies? Any chance that there's a vested interest?

I'm not someone prone to headaches, and these were of a very specific type - a deep, painful ache in both temples - which would begin about an hour after switching on the laptop's wifi. It doesn't happen when using the home plugs with the laptop's wifi switched off.
For the record, I'm also sensitive to X-rays (they make me feel sick), but not MRI scans.

Odd.

PS Let's not get into the hazards to radio frequencies some say are caused by home plugs. Message already received, but irrelevant here.
