The following was developed as a mental age assessment by the Harvard
University School of Medicine, Department of Psychiatry.
Take your time and see if you can read each line aloud without a mistake.
The average person over 40 years of age cannot do it!
1. This is this cat.
2. This is is cat.
3. This is how cat.
4. This is to cat.
5. This is keep cat.
6. This is an cat.
7. This is old cat.
8. This is person cat.
9. This is busy cat.
10. This is for cat.
11. This is forty cat.
12. This is seconds cat.
Now go back and read the third word in each line from the top down and I bet
you can't resist passing it on!
Ok, I've hurt my brain. I concentrated really, really hard so I could read it correctly. Why did the blonde stare at the orange juice container? Because it said concentrate. I need to go home now!
