This was developed as an age test by the R&D
Department at Harvard University . Take your time
and see if you can read each line out loud without a
mistake. The average person can't do it! This is
really difficult, not so easy, so be careful.

5. This is keep cat
6. This is a cat
7. This is fool cat
8. This is busy cat
9. This is for 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.
