Brief notes on Donald Trump: is he above the average?

Donald Trump is a controversial figure who arouses the sympathy of some and the hatred of others. The news about Trump often takes a propagandist tone, others defamatory. One of the main issues discussed now is if he is fit to be President. I would like to raise a few points that I did not see commented by anyone in the media.

Every political commentator knows that just achieve the US Presidency already puts him above the average. The level of pressure that candidates pass would not be tolerated by the great majority of the population, so this fact shows he has a remarkable mental stability. That’s the point I would like to highlight: Donald Trump's ability to withstand criticism from around the world and to continue working at age 71 does not show he has a mental strength above the average?

How many times have we heard that people close from us or even famous (by media) collapsed because, for example, the end of a marriage (they say that was the case of Dolores O'Riordan), a professional frustration, for lack of money etc, and ended up with a heart disease or depression or other medical issue. Donald Trump has been for at least 30 years constantly in the media and often being detested. I believe this should be exhausting, but despite of that and, also, accompanied by bad eating habits and no exercise, he is healthy and he is working at age 71. Unless if proved he is a psychopath and has no feelings, wich does not seem to be the case, indisputably, his stamina is striking.
