I walked into our living room just now holding a check in my right hand to ask my wife if she had an envelope. She said she did and started walking to her office.
I passed the check from my right hand to my left and took a step to follow her.
An instant later I felt something in my right hand and turned my head to see what it was. It was then that I realized that the message telling me that the check had left my right hand had just reached my conscious brain.
I don’t think I would have noticed that sort of thing while younger.
