This man had a superpower I wish I had. You know what? The ability to ignore sound waves. :)
A 'do not disturb' signboard was the only thing missing.
In the 10+ minutes that I spent there, at least 50 people walked up and down those flight of stairs but this guy did not move an inch.
Either he had too much on his mind or too little. Those are the only 2 scenarios that let a man sleep as peacefully as this.
