I’m glad the president of our country feels so proud when he passes his cognitive tests. It is important to know the difference between an elephant and a giraffe. But why won’t he show us the clock he’s supposed to draw. These are the tests they give to make sure brain matter is working properly. The fact that he is given these tests often is not a good sign. Just like his MRI. These are tests that look into the problems they are already aware of. So again, why the many, many cognitive tests?
