Today's 'User Friendly' is spot on, commenting about a trend in our society that 'natural=healthy'. I've written about this before. Whilst I'm keen to avoid E numbers and all sorts of unneccesary things like that, I'm not naïve enough to assume that 'something with a chemical name is bad' or that 'if it didn't grow from the ground it is bad'. I might cite dihydrogen monoxide as a counter-example in the first case, and deadly nightshade in the second.
Well done, UF. 'Go hug a shark' is officially my favourite phrase of the day (though it wasn't used in that form in the strip).
Of course, dihydrogen monoxide does have some problems... it's a chemical found in virtually all tumours for a start.
