High Sensitive

As soon as you handle technical stuff that is a little bit expensive you put big orange stickers with "High Sensitive" on it and store it on a cushioned flight case.
On the other hand if it comes to human beings no one cares about handling with care.
I guess life would be easier if one would have such an orange sticker on the forehead on bad days indicating that today there's a bit more sure instinct required.
Yes, I know there are a lot of orange-sticker-like gestures in human behaviour that one could read. But I'm neither good at using that gestures nor in spotting them.
