Does Jack Cafferty Suffer From Old Age Dementia?

I seldom watch CNN, but when I am forced to watch it in my health club I often hear Jack Cafferty remarking about John McCain's age. Ageism is a form of bias, and the low, tasteless quality of the pro-Obama media exhibits itself in Cafferty. Problem solving ability peaks at about age 20, but knowledge of how to solve problems, i.e., experience, compensates for loss of mental acuity. There are few breakthroughs in math or physics made by those above age 30, but there are a large number of literary, artistic, philosophical, legal and business breakthroughs made by old people.

I looked up Jack Cafferty's age on Wikipedia. He was born in December 1942, while John McCain was born in August 1936. The difference between Cafferty and McCain is a tad over six years. Perhaps it is Cafferty, rather than John McCain, who suffers from senility.

Unlike Cafferty, I am not one to make ageist comments, but Mr. Cafferty lives in a glass house and has been throwing stones. So here goes. I wonder if Cafferty gets the news right since he might be suffering from old age dementia. Can we trust Cafferty to be a good newscaster? He seems illogical. He is past the age for ordinary onset Alzheimer's, and his lack of awareness and tastelessness suggests acceleration that condition.
