I'm not nine anymore, and I missed that today, when I finally found the screwdriver that could fix my glasses. It took a few tries to get the screw lined up right, and I had to squeeze very carefully to get the holes in place. I had to take off my emergency backup glasses and look at the screw ever-so-carefully to make sure it was OK to start moving the screwdriver.
I still have strong, capable, dexterous hands. But I'm not nine.
