I have a question out of curiosity. It is just something I found out/discovered: if I fold my hands into each and let my two index fingers (see picture) be in parallel then they will eventually come closer to each other and touch.
Another thing I found out: if I fold my fingers on my left hand slightly and then with my right hand squeeze the wrist of my left hand (see picture), then the fingers of the left hand will fold more and more. Is this a coincidence of general?
