What percent of your time do you spend waiting?

Waiting on hold on the phone?
Waiting for medical appointment?
Waiting for payday?
Waiting for clothes washer drier?

What do you do to fill the time?
What other things can you add to my list?

Humor and serious answers welcome:

I seem to be always waiting for something or other.
I don’t know the exact percent, but I believe it is high.
