Batteries

I picked up a pack of batteries this morning. Not really exciting, but I am kinda worried about the general level of intelligence of people in a developed country where you need a colour code on batteries so you know which ones fit your electronic kit.

Seriously, if you can't tell the difference between a triple-A and a D cell except by the ring of colour about the end of it, you really shouldn't be trying to put batteries onto things. In fact, you probably shouldn't be allowed out in public unsupervised. If at all.
