I enjoyed watching it, but building it took days of work and he didn't have to care about his well being in the meantime, judging by how clean he was he spent his off time in civilized world. Also people don't realise how weak they are when they're hungry until they have nothing to eat, that guy probably had a nice, solid breakfast each morning before shooting the video.
Weird to think that the process hasn't really changed that much. Just different materials. and even then, sometimes we just use refined versions of the same materials.
Amazing, but I've been the whole video thinking about the roof. Isn't it too weak? I mean, what if the wind blows a bit fast? Wouldn't the tiles fall apart? I'm not a survival expert though, maybe he did something to avoid that, I don't know.
