Horizon is there to entertain people who watch telly, rather than make them prove themselves in some kind of intellectual fight to the death. Admittedly, when I was young, science on TV gave even clever folks the sort of epic nosebleed that normally required your being hit on the nose by an agitated rhino. Not sufficient to have you bleeding, they'd then punch you in the brain with Mr Schrödinger's really hard wave equation, leaving you mentally gasping and intellectually winded. That's why TV used to look black and white, the whirling vortex of intellectualism would stuck up so much brain power that you weren't left with enough left to process colour. That was proper science telly, back when O Levels were hard and A Levels were so tough that they were genuinely fatal (coincidentally, they became easy the year after I completed them).
I want to know what my cats do. OK, they sleep a lot, but you've got to think that maybe they're teleported their brains somewhere while they sleep, perhaps to some kind of undersea (or possibly orbital) HQ where they discuss their next phase of human-behavioural modification. But when they're in-body, mine are out there somewhere. For all I know they're taking in a west-end show or pulling on floppy blond wigs and standing in for Boris. I want to know. Plus there's several cats that hang out in my garden. It's all a bit sinister. I suspect they get together and act French. No, I don't just want to know, we as a people need to know what our felines are doing.
Mind you, the threat posed by cats is nothing compared to that of the dolphins. Something should be done about them. I advocate turning the sea into treacle to slow them down.
