Death: $15, age has always been an issue.
Age? We have had other former Presidents living into their eighties and nineties and maintaining high levels of activity. Let's put it this way: Carter has a better chance of reaching One-zero-zero than Trump has of reaching four score.
This is a good reference:
https://www.ssa.gov/oact/STATS/table4c6.htmlOn average, someone his age has a 3% chance of dying in the next 12 months. However, a lot of causes of death are greatly minimized due to his position. He has agents protecting him 24/7. He has doctors who could attend him constantly should a health problem arise. Simply the fact that he has no known serious problems drops that chance below 3%, even if his obesity does raise it a bit.
