When I was young I was called a rugged individualist. When I was in my fifties I was considered eccentric. Here I am doing and saying the same things I did then and I’m labeled senile.

Our reading
An editorial interpretation.
Here the speaker jokes that the same behavior keeps getting new labels as the years pass: admired as rugged independence in youth, tolerated as eccentricity in middle age, dismissed as senility now. The humor is that nothing changed but the audience's expectations of age.
