Oh I'm not arguing it's a hot temp and exerting yourself in those temps is very much a death sentence; especially without water. I'm saying that many people in the world have lived through those temperatures. Research studies have a way of making things a bit more dire than what is normally human survivable, probably for legal/medical moral reasons.
The US military definitely has rules against 40+ WBT and state how many hours of work per hours of rest we could have in high temp+humidity levels. However, I, and anyone who had to deploy or live in East Africa (like Djibouti) or the Middle East can definitely attest, 50WBT is survivable for 8 hours days. Again, not talkin' elderly or sick persons.
I don't want to be rude, and I completely am all for combating climate change, but 39C is not baking your insides...
I have been deployed to multiple places that were 52C (125F) in the day/night with high humidity levels, in full long sleeve/pants for 8 hours at a time. 39C (102F) is hot, but not bake you from the inside type of hot.
Elderly and sick are people not included in what I said above for obvious reasons.
Crazy enough, the Bible wasnt written all at once. The Bible was written over a span of approximately 1,300 years (depending on your historical, linguistic, and theological beliefs of course).
The Old Testament, also known as the Hebrew Bible, was written between approximately the 12th century BC and the 2nd century BC.
The New Testament was written in the first century AD, from approximately AD 50 to AD 100.
So probably a bit of the old testament could have been written while under the influence of mushrooms as that's when we were experimenting with wild mushrooms.
But what do I know, the picture says I died from mushrooms.
I work at NASA and we use redhat a lot for development work.
