Beware!

I hadn't the first idea that cherry stones contained cyanide.  A man from the north-west of the country found out the hard way when he crunched up a few and ended up in hospital having, according to the hospital, consumed a potentially lethal dose of the poison.  And it's not just cherry stones it seems - the stones of apricots, peaches and some other fruits are similarly poisonous if chewed.  Why anybody would want to, mind you, is another question.
