Is that the sound of the warp drive in space? It certainly isn’t the sound effect the explosions in space use.
If it wasn’t for artistic license, they could have gone with what happens when the inertial dampers fail in the spaceships in David Weber’s books, which is a more realistic outcome (assuming realism is what you’re looking for in a setting with warp drives and inertial dampers), but writing off the crews of ships that don’t matter to the storyline in a red paste probably wouldn’t go over well in a family drama. About as well as people sitting around in a pitched battle with the occasional hum or shudder.

You won’t get an answer because he’s wrong. This link shows some stats about heat stroke in America. People under 5 years old die at a rate of 190 per 100k, the it craters to 27 per 100k from 5 to 14 and keeps climbing from there, peaking for those between 55 and 64. Note that deaths between 35 and 44 are more than half that of the cohort most likely to die of heat stroke, not people you wouldn’t consider in their best condition.
Everything about that chart says that unmanaged heat is very dangerous and as we get older it gets harder to handle, at least once we are over the age of 5 and our heat regulation mechanisms have matured.
This is the same excuse anti-vaxxers use for why it’s okay that children and old people die from the flu. “The flu isnt dangerous, it only kills the ones who are too weak to survive.” Of course, kids who don’t die of the flu live just fine for decades, whether they avoid doing so by luck or vaccination, and while seniors won’t necessarily live for decades if they avoid the flu or heat stroke, they can still live for years. Here’s an abstract talking about morbidity for people over 80. 23.9% mortality for those without the flu vaccine vs 20.9% for those with, for total morbidities. There is a significant reduction in all morbidities if these really old people just don’t get the flu.
