Moving sensor light

I understand that technology is a good thing. That technology improves our lives, etc.
But I hate the invention of the lights that switch on and off according to movements. Yes, they are great, they help in saving energy. But the point is that if you don't move, they switch off. It doesn't matter if you are there doing something. You don't move, so there is no need for a light.

This is generally annoying. But it gets even more annoying when it happens while you are in the bathroom to do something that generally does not require a lot of movement. So, I am there, doing my things and puff, the light goes off because I don't move and suddenly it is all dark.....I don't know who had the brilliant idea to put these things in toilet rooms, but I really find it very impractical!
