The Age in Your Head

I'm 53 years old. I feel 36.

This past Thanksgiving, I asked my mother how old she was in her head. She didn’t pause, didn’t look up, didn’t even ask me to repeat the question, which would have been natural, given that it was both syntactically awkward and a little odd. We were in my brother’s dining room, setting the table. My mother folded another napkin. “Forty-five,” she said.

She is 76.

Why do so many people have an immediate, intuitive grasp of this highly abstract concept—“subjective age,” it’s called—when randomly presented with it? It’s bizarre, if you think about it. Certainly most of us don’t believe ourselves to be shorter or taller than we actually are. We don’t think of ourselves as having smaller ears or longer noses or curlier hair. Most of us also know where our bodies are in space, what physiologists call “proprioception.”

Yet we seem to have an awfully rough go of locating ourselves in time. A friend, nearing 60, recently told me that whenever he looks in the mirror, he’s not so much unhappy with his appearance as startled by it—“as if there’s been some sort of error” were his exact words. (High-school reunions can have this same confusing effect. You look around at your lined and thickened classmates, wondering how they could have so violently capitulated to age; then you see photographs of yourself from that same event and realize: Oh.) The gulf between how old we are and how old we believe ourselves to be can often be measured in light-years—or at least a goodly number of old-fashioned Earth ones.
