I have flown from London to San Francisco on a non-stop flight at age 68. That long flight was brutal on my body. My butt was sore, my feet swelled up, and I was dead tired at end of that flight. Amazing mid-70’s Trump can endure those long flights to so many places. Of course he is flying in Air Force One, while I am flying tourist class. But still those long flights are very bad for seniors.
He does have a lot better seating than you.
