This is NOT a joke. If you were able to pass these 3 tests,  you can cancel your annual visit to your neurologist.
Your brain is great and you're far from having a close  relationship with Alzheimer.

Got em. I have a problem that I can see in 3D very easily.  With the ("0") they all run into one, so have to focus.

Took about 10 seconds to find them all.
Brains OK, shame about the rest of the body.

I'm good for another year.

[Paint Your Wagon]

  Got em, O was harder.  I can easily  see in three D and the Os appear as 3D.
