Is There Something Important About Physical Proximity?

Could it be that people my age and older aren't really good at forming on line relationships? They still do it related to physical geography. But perhaps the younger, digital generation, they'll be very comfortable making relationships on line. And this effect could decline with time. Is there any reason to think there's something important about physical proximity? Yes. Why i see a lot of really good scientific ideas here, but i don't know where to begin.
