Today I did a foolish thing, but I am fine now. I went on a bicycle ride (not alone), and it was 102*-105* out. I had water, had been drinking water all day, and a hat and sunglasses on. At first I was fine, pushed myself pretty hard on the ride, but after quite a few miles and about 40 minutes, I realized my mistake. And, I still had to get back. There was no shade, the sun was bearing down, I was in the boonies, and I knew I had made a completely poor choice. The whole time after I started getting dizzy, I was thinking about this couple and the things I've read here. For such a short stint in evil conditions, I could see that a person would quickly diminish in thoughts and abilities in a relatively short time. I was only out there for about 1 1/2 hours overall, but since I had worked myself so rigorously, it really kicked my butt. After stopping a ton along the way back, and going super slow because it's all I had left in me, I got to my driveway, stripped off everything that wasn't covering my naughty bits, and got myself inside the house. Someone else went out and get my things and put my bike away. I could barely walk, and I just didn't care. I really was not too far away from a heat stroke, but that didn't happen so no worries now. All the riders had some level of heat issues and regrets on our ride today. It was foolish. I can't image doing it all day, day in and day out, with little to no water.
I guess my main point to this posting is to say, if they are out in that desert, I do not think they are still alive. I don't see how they could be.
