…to do this and that!

Have you ever thought about labels on technical devices? I mean, they might be helpful to understand how to handle it. The labels on gamma-ray detectors tell us, for example, which high voltage to put, labels on notebooks tell us, that they are designed for a certain operating system (and they are not even removable when we use other operating systems…) but sometimes these labels, tell us directly how to behave…

For instance: “Handle with care”, or “Do not shake” or the like. But there are labels, that try to reach our conscience, while they are telling us things, that are likely to be forgotten:

So, do what the labels tell you whenever you can!
