JR Speaking!

If you have ever sat close to the driver's cabin on a train in Japan, you may have heard the driver talking to himself. 
What is he saying? Well, I guess he is giving himself instructions to check things before the train departs from a station.
Unusual? Well, research has shown that this spoken action can reduce the incidence (number) of driver errors as the spoken word forces the person to check properly.
I can understand the logic, and actually, I do the very same thing when I leave the house in the morning to make sure I have everything important that I need.
Usually, I say 'phone, keys, computer, food, water, trousers.......' Well, apart from 'trousers', everything else is true.
Do you ever do this?
