I recently heard that the nerves controlling the pinkie and ring finger are intertwined to the degree that it’s almost impossible for most people to move the pinkie and ring fingers without the other. Does it count as “independent” if one twitches while the other does the real moving? I think I may finally be special!
Place your hand palm down on a flat surface (like a table).
Put your middle finger under your palm, leaving your other fingers outstretched. (Kind of like throwing the heavy metal horns, but with only the middle finger tucked in)
You can probably lift your index finger or pinkie finger up alone no problem. Lifting your ring finger alone will probably be hard, if not impossible, as long as you keep your middle finger tucked under your palm.
