doctors have concluded that if you can 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, than the right half of your brain is functioning normaly.
if you find the man between 1 minute and 3 minutes, than 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, than the advise is to look for more of this type of exercise to make that part of the brain stronger!!!
and, yes, the man is realy there!!!
