As I grow older, I pay less attention to what men say. I just watch what they do.

Men of age object too much, consult too long, adventure too little, repent too soon, and seldom drive business home to the full period, but content themselves with a mediocrity of success.

Men are like wine - some turn to vinegar, but the best improve with age.

I suppose when they reach a certain age some men are afraid to grow up. It seems the older the men get, the younger their new wives get.
