Fwiw, McDonnell was, until last year, a Democrat. The article mentions it towards the end, but, in essence, he’s pro-life due to his religious beliefs. He refused to block the GOPs push to enact far-reaching abortion restrictions. The Democrats censured him for breaking from the party line. He swapped over to the GOP shortly thereafter.
So, good on him for having a spine to vote his convictions regardless of party affiliations. Very no good, bad, don’t do it of him to be convinced his particular supernatural fantasies have any bearing whatsoever on the bodily autonomy of his constituents.
Would the sensation be similar to being at high altitude without oxygen? There is a Smarter Every Day video from several years ago where the host conducts simple cognitive and motor function tests in a pressure chamber which simulates high altitude atmospheric conditions. Within a couple of minutes of being off oxygen, he’s suffering from hypoxia and is unable to either continue the tests, or to mask up, despite being told the he will die if he doesn’t secure oxygen. Admittedly, it’s incredibly chilling to see the guy rendered so helpless, but, from his perspective, it did not seem particularly traumatic. As I understand it, if he had not had his mask applied for him at that point, he would have lost consciousness and then died in his sleep shortly thereafter. All things considered, not the WORST way to go. Beats getting stuck in that compartment with a leak and eventually drowning.
