ADDED: 14 seconds is a long time to look at someone. Singh sounds ridiculous mostly because he specified a number and it's not a more normal-seeming number like 10. (I checked the Wikipedia article on the number 14 to see if 14 might be special in India, but the closest I'm seeing is the number of years of Rama's exile in the forests.)
If you look at articles on making eye contact with people, you'll see that even a quarter second can make the difference in moving a glance to an expression of interest. Example:
My man tells me that construction workers in Canada are told to obey the "3 second rule" by their employers... So basically it's one second to look at the girl, another second to study her and decide if she is pretty, and another second to enjoy the view, before returning eyes to the task at hand. Anything beyond that is creepy and likely dangerous in some way. I would agree....AND: "Staring into someone’s eyes for as little as 10 seconds can be an intense experience of connection, or one of discomfort. So what happens when you look into a person’s eyes for 10 minutes?... A new Italian study finds that when people look into each other’s eyes for a long period of time, they often experience symptoms of dissociation — including feelings of detachment from one’s body and from reality — and full-on hallucinations."
Subway staring is a big problem where I live (Toronto). It is often the result of "DeathFace", which is a common syndrome out here affecting the overworked, causing them to forget they are in a subway and stare off blankly into what they mistakenly think is space, but usually is people.... I am often the victim of these types but have learned to ignore them. I pity them, actually....
