I am old. I know lots of old people. I lived in Florida for years and now live in Allegheny County Pennsylvania, the second oldest population in America. I am an expert on old, and sir I can tell you that age don’t make you smart.
Criticize a person’s ideas based on facts and logic or even faith, if that what drives you, but by God don’t discount their ideas just because you’re older. Ever heard the expression, no fool like and old fool?
I’m using logic. At 19, you haven’t lived enough to be wise to the ways of the world. Age doesn’t make you smart, but youth certainly contributes to foolishness!
