Ageism is hiring a 25 year old instead of a better qualified 55 year old. It's not "ageism" to say that an 81 year old or a 78 year old might not be able to handle the world's most demanding job.
In 2015 I asked someone I deeply respect (attorney & CPA) who she would vote for. She said, "neither. They are both too old. They're my age I ought to know". Again, in 2015.
I remember my grandfather commenting on this in 1984. He was around the same age as Reagan and said that he wouldn’t have the energy to do the job at that age.
