Doctors commented 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 can not find the man after 3 minutes, the advice is to look for more of this type of exercise to make that part of the brain stronger!!!
And, yes, the man is really there!!
