It is quite easy to watch a crazy brain story on television or in the web series. People have also read some brain stories as well but for this week's discussion, I would like to tell a story narrated by my colleague. My friend named Roberto along with his trip mates went on a remote area of Semuc Champey, Guatemala. Their team consisted of 3 males and 2 females. On their way to Semuc Champey, Guatemala, they found a small river, it is better to say a stream, and they decided to spend some time there. One of their mate named Laura got in the river for swimming and the below the water there was a sinkhole.
