This is bizarre - after you find the guy - it's so obvious.  Once you find him -

Doctors have concluded that if you find the man in the coffee beans in 3 seconds, your right half of your brain is better developed than most people. If you find the man between 3 seconds and 1 minute, your 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, 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!!!

I think I have found him, but am not sure!
