I thought it was only me. "Wow, this silver solder sure is stiff." Or, I join the Lumosity 'brain enhancement' site only to find that not only I am WAY loooow in the 55-59 age group, but there may be no help for me anyway. Stupid Lumosity guys...
We do that one around here all the time. I think it's a sign that it's time to straighten up the work bench a bit. That makes me think of a safety thing that people should remember - if you are soldering on, and then switching on a circuit to test it make sure your solder is spooled up and not trailing over you work where it might hit a live terminal. I have to check myself on that one every once in a while.
