I constantly pump into things. I decided to measure my clumsiness. During one day I counted the times I accidentally hurt myself. I only counted the times when I reacted "ow www!" and I felt the soar skin several seconds later. I got to seven. A few days later I recounted and also got 7.
I hit my hand on the corner of a wall
I scratched myself
I stung myself with a fork
I hit my head on the ceiling of a bus
I hit my toes against the door
And there were lots and lots of times when I just pumped into something, but didn't get hurt. Fortunately I don't bruise easily.
Is this quality (being accident-prone) unique, scattered among the types or very common among INTjs?
