Low Battery

Speaking of digital world it has certainly changed our perception of life. Especially in our every day life. For example time to time I catch myself talking about “low battery” in terms of tiredness or exhaustion. There is no connection between me and anything digital. I obviously do not have a battery attached or insert to my body. By saying “I have a low battery” I described my physical and mental state meaning that I am unable to do anything anymore and simply need to have a rest or sleep. Same as I would say that I need to “recharge” or “charge” myself.
