Well… yeah. Ultimately, Jim Henson died because he couldn't break out of that stubborn, usually male belief in his own invincibility. My husband has that problem too. So did my dad. And my grandfather. All of them had medical crises because they thought they could just shake off some ailment. Thankfully, they didn't die from their stubborness.

But, the specific, medical reason Jim Henson died was organ failure from sepsis due to complications from pneumonia.
