Let's get your brain to work!
Can you find the man in the picture in 3 seconds?
According to medical research, if you find it in less than 3 seconds, your brain is developed above normal brain.
If you find it in a minute, you have a normal developed brain.
If you find it between 1 and 3 minutes, your brain is responding slowly. Protein in-take might help.
If it takes you more than 3 minutes, your brain is responding too slow and perhaps more exercises like this might help you to develop that part of your brain.
It is not a joke, the man is really there!
