Jim Kwik wears brain-graphic shirts to remind people to care for their brains the way they care for visible things like hair and skin. He argues the brain controls everything, so it deserves the same attention and love you give to what you can see.
When people see me wearing brain shirts all the time or pointing to my brain, the reason why I do that is because what you see, you take care of. You see your hair, you take care of your hair. You see your skin, you take care of your skin. You see your clothing, you take care of your clothing. You don't see your brain. Exactly. And that controls everything. And so when I point to the brain or honor it with the shirts, just like people have their emotions on their sleeve, you know, I have my brain on my chest because I want to put it forefront to remind people to love their brain.
