Doctors have concluded that if you find the man in the coffee beans in 3 seconds,
the right half of your brain is better developed than most people.
If you find the man between 3 seconds and 1 minute, the right half of the brain is developed normally.
If you find the man between 1 minute and 3 minutes, then the right half of your brain is
functioning slowly and you need to eat more protein.
If you have not found the man after 3 minutes, look for more of this type of exercise
to make that part of the brain stronger (see links below).
