Age Lag

Typically for people who are loners and/or don't have much of a social life. This is the phenomena that causes them to falsely think that everyone they see whom they would want to associate with is their peers, or even in their age group. For example a middle age man looking at a young woman in her early twenties in college AND wondering if she'll "dig" him. He may be suffering from a case of Age Lag

My Hermit uncle is blushing at his nieces friend, I think he might have a case of Age Lag
