They stand looking out at us from ads seeking donations for cancer research and farmers, from ads trying to sell us outboard motors and jogging shoes, and I've been questioning the purpose. I mean, what has a pretty young woman got to do with cancer research or outboard motors? Does she herself wonder why she's paid to stand there smiling and empty headed? Probably not.
If in these enlightened days we see age, shape, size and colour as telling us nothing about the person within, why don't we have an obese man or woman draped over the outboard, why not a craggy, crippled farmer standing in the stubble? Or at least a teenager with a few squeezed zits?
Advertisers know what works and what doesn't or they're not advertisers for long, and so I can only assume that the presence of a pretty young thing is more likely to induce us to buy a motor bike than the presence of some pretty old bloke like me. Why would the presence of anyone affect the decision to buy or not to buy?
Have a look - they're everywhere, these pretty young nothings who probably couldn't whip up a half-decent breakfast for the man reaching for his wallet.
I'd hoped that Big Brother's very effective exposure of the inanity of youth would cure us of this cult of youth and beauty, but the cult is now booming and ubiquitous.
We do seem to see something in youth and beauty, something that is not there. What do you see?
