Right handed ot left handed?

I tripped today and broke my fall with my left hand, leaving it slightly injured. This reminds me of a mystery I had been trying to solve all these years. Am I right handed or left handed?

Most of the time I would not know which hand I would use to perform a new task until I do it.

I eat and write with my right hand and basically perform most other tasks with my left, although there are exceptions. For example, I can only use a knife, scissors, needle with my left hand. I carry heavy objects with my left hand. I throw a ball into the ring with my right and play badminton with my right hand. But I hold a hockey stick with my left hand and play darts also with my left hand.

I remember I was in this fancy restaurant in Bonn, Germany some years back. I noticed that whenever I placed my drinking glsss back on the table the waiter would promptly rearrange my glass back to the right hand side. I then realized that I can only hold a drinking glass with my left hand and gave the waiter so much trouble.
