Staying on the subject of Dr Who and the Vashta Nerada as featured in the latest episode (the Vashta name means "shadows that melt the flesh"), these bad boy shadows are in fact (or in fiction) microscopic beings that swarm all over the universe and eat meat in a rapid piranha kind of fashion but without the trashing and biting. If you're worried at all about this tricky creature(s) then perhaps it's better to sleep with the light on (as if that would help).This link may explain more and also lead into all sorts of murky truths and facts about Dr Who, most of which are of no interest to me at all: http://tardis.wikia.com/wiki/Vashta_Nerada
In a (for us strangely) TV dominated weekend Lost reached a series finale climax last night. Lots of lost type things happened, ending in that modern time-lapse kind of way with the Island going of every body's radar, the ship blowing up, the helicopter ditching and the confused (but never hungry) survivors making a pact to lie about their experiences (groan!). Now they are back amongst us, the critics, the bewildered viewers and the many millions more who couldn't care less. So long and thanks for all the endless enigmas.
