For the first time in my life I feel sorry for insurance salesmen. The Financial Services Authority has taken a big red pen to their use of the words "save up to £200 with our insurance" in the text of their sponsored links. That's because the FSA is concerned that these advertisers fail to substantiate the percentage of people actually receiving the savings. So the FSA says these ads are misleading.

There are two things I don't get. First, is anyone actually misled by such ads? If I see the words "save up to £200," I have enough shopping experience to know that I'm unlikely to save the full £200 but that some people will (or should). I don't object to the ad when I learn that I won't save the full £200. (I'm carrying 3 points on my licence; I don't expect the ad to know that). It's surely just a ubiquitous advertising puff. Second, how do you write compelling copy while also substantiating that £200 saving in two lines of text, each with a maximum of 35 characters? "Four per cent of customers saved £200" won't make me click.

Should we be sending our kids to school in tinfoil hats and ET-style zoot-suits made of lead? The BBC's Panorama programme might have us think so: they have made a big song and dance about the fact that wireless internet (WiFi) signals are three times as strong as mobile phone signals.

Well, hold off on the cookware millinery, it is unlikely that our kids' brains are going to be fried quite yet.

Stem the tide of parental outrage for just a moment and ask yourself: should we really be surprised that a wireless data network signal is stronger inside a classroom it is designed to cover than a mobile phone signal is outside?

And given that the World Health Organisation (WHO) says that mobile signal strength ranges from 0.02 per cent to two per cent of the government guidelines, shouldn't we be blowing fat raspberries at Panorama and saying: fine, but three times almost nothing is still not very much?

We should. Common sense tells us that all these radio waves infecting the air just have to be frying our brains. We all have a touch of the Cassandra about us, wailing that we can't have all this mobile fun for nothing, there's a reckoning in the post and we'll all be sorry.

Well, common sense also says two tonnes of metal shouldn't fly through the air and that cheesy beans should be horrible, but common sense isn't always right.

There may well be evidence we haven't yet found that says that mobile phones and WiFi networks will send us all mad, but the fact that a wireless network is stronger than a mobile phone signal just isn't it.

So put the tin foil away - much to their dismay it's just the normal school uniform for the kids tomorrow.
