Around the age of 50 I became very sensitive to and aware of personality "types". I saw or met different people whose faces looked alike, and I studied them closely. I was CERTAIN that their similarities went beyond the physical, and I was right.

Today, whenever I meet a new acquaintance or a new student, I search my mental picture files and compare them with others I'd known who look like them or fall within their type. Now I know whom to take in and whom to drive away. And I am never wrong about this.

I think, one must be in midlife in order for this ability to be activated within oneself. The only other writer I know who believed in this--and wrote about it more than once--was Agatha Christie.
