If one is carrying a pack with the capacity in the video, then properly chosen gear will allow positively comfy existence in almost any conditions - luxury survival, including packing a nice small conventional stove which will prepare almost any hot food you might prefer, including the iconic nice cup of tea. Many small tents or even elaborate bivvy sacks could be incorporated as well

The flameless hat pack shown in the video looked like the smaller Trekmate brand, whose flameless cooker I purchased a few weeks ago - very nice unit. it does a nice job of cooking, including the very best omelet I have ever prepared, but the packets are kind of pricey - not recommended for routine use.

Conspicuously missing is any discussion of finding shelter - the assumption seems to be that the victim will simply plop down wherever and gut it out. Looking around just a bit can make an enormous difference. Finding a rock overhand or a down tree, even just a few feet away, can improve the situation a lot. I have found that the very best shelter, exceeding even the most expensive tent you can obtain, is a nice dry rock shelter or cave mouth (at least when rattlesnakes aren't denning). Survival is the quite easy, if not downright cushy. My very best nights in the outdoors have been spent snugly camped in rock shelters, with a nice compact camp stove.

Of course, rock shelters are a lot more common in the American Southwest than on the windswept moors of Merrie England...
