Here was the "what if" question...
What if we had seven fingers on each hand?
We could name our fingers each day of the week. We could flick people off by calling them days of the week instead of cussing them out.
If you were clumsy you could say "sorry I'm all weekends".
How would seven fingers on each hand affects sports?
You would have more fingers to put rings on.
What would a keyboard look like?
What new things would come into existence?
How would it change business and profession?
