Yes they make life very convenient in so many ways and I don't know how I could cope without either, but something about wireless signals passing through your body all the time is quite worrying - especially mobiles which you hold right next to your brain effectively.
I'm sure there are studies by the World Health Organisation claiming the safety of these things, but they did the same with tobacco - it was once considered good for you.
Thoughts?
I'm not sure how exactly either could be considered harmful. As in, what is the medical process that makes you ill from them (or is suspected to)?
Mobile phones and wifi are non-ionising radiation. Non ionising radiation can't affect DNA.
