Then you have my brain... you say to visualize a hammer, and my brain asks a question... "which hammer?" and then proceeds to scroll through images of every type and style of hammer from every point in human history that I have ever witnessed. Starting with a rock, a wood mallet, a hundred types of smiting hammer, and all the way to a modern claw hammer from the hardware store, which is what 90% of people likely imagine in their mind.
I wish I were joking...
