Brain researchers have found out that if you can see the man in the coffee beans within 3 seconds, your right part of your brain is better developed than the average. Between 3 seconds and 1 minute, and your right part of the brain is at a normal state of development. Between 1-3 minutes, and the right part of your brain is operating slowly and you need to eat more protein, or perhaps omega 3. If you still haven’t spotted the man after 3 minutes, brain researchers advise you to look for more exercises to train the right part of the brain.
