the chin problem

A line from Richard Russo's Empire Falls made me feel a little bit better about my lack of a chin. It's not just me. It's my heritage.

In natural light she looked rather pinched, and in the manner of a great many women of French Canadian ancestry, she lacked a chin, as if someone had already pinched her there.

Why don't men of French Canadian descent lack chins is what I want to know. Harumph.
