Relative risk

I'm mildly amused by the reaction to the WHO research on mobile phones, which may be roughly summarised as "OMG! Phones are going to kill us!"

And yet the WHO has parked cell phone use as "possibly carcinogenic" in humans - on the same level as petrol exhausts and safer than diesel exhausts (which are "probably" carcinogenic). But nobody looks at cars and thinks of them as a source of cancer, or that we should ban their use around children. Indeed, what's proven to be dangerous about mobile phones is their use whilst driving.

By the way: June 14 is world blood donor day. Find your nearest centre, open up and have a biscuit after. You'll feel better and someone else will live.
