Exactly my point. Glad you noticed.
Uh-huh. Again, you're implying the two flight profiles and the resulting strain on the pilots are the same --they aren't.
Leeward was flying 50' off the deck at 500mph and pulling 4-6 Gs around the turns. Yeager was flying straight and level at high altitude. Not even remotely similar.
Yet you would have us believe that flying a P-51 around Reno in race conditions is as easy on the body as flying straight and level.
The point you're avoiding is that as people age, their reaction times slow and they can't hold up to the same physical strain as younger men.
So, why do you think the USAF put Yeager in a two-holer instead of a single-place F-15?
