I count things. Like I count the things I pick up and I’m heading out the door. I count the stairs. I count things as I do them like they were steps of a procedure.
Son does the same thing but I think we ingrained that in him. We counted everything with him when he was very young to teach numbers. Count steps, count cars in the parking lot as we walked to the store, count the pushes when swinging, etc.
The extremes of explanations ranges from you’re clumsy and drop things by accident all the way to you have a tumor.
I’m not saying you have a tumor but if this is something you’ve noticed enough to recognize it as a quirk, I would mention it at your next appointment with your PCP or take this as a sign to make an appointment with your PCP for a check up and to talk about it.
