Not long after publishing his first book, London designer Thomas Thwaites found himself with no real job and in relationship trouble. His book, The Toaster Project — about his attempt to build a toaster from scratch — was a huge success, but he found the whole business of being a celebrity thinker a hard act to follow.
To be human is to worry about getting by, doing better, finding love and accepting the march of mortality. Thwaites decided to try to escape the burden of being human — and he would do it by becoming a goat.
"Human life can just be so difficult," he tells NPR's Scott Simon. "And you look at a goat and it's just, you know, it's free. It doesn't have any concerns."
Thwaites' new book is GoatMan: How I Took A Holiday From Being Human.
On how he was able to walk on all fours
I made a few prototypes myself of this kind of walking frame, but found it actually to be much more difficult to get any kind of vaguely comfortable quadruped walking exoskeleton. And so [I] decided I needed a bit of help and I ended up spending a weird afternoon in the dissection room at the Royal Veterinary College to sort of examine the differences and similarities between a human anatomy and a goat's anatomy.
On eating like a goat
Obviously, goats eat grass. And any human can eat grass, but the trouble is we can't digest it. So I decided I would have to make myself like an artificial rumen. And the rumen is the kind of ... bit of a grazing animal that contains all this weird bacteria which actually lets these animals break down the tough fibers in grass and digest them. ... And I kind of thought maybe I could infect my own gut with the bacteria from a goat's rumen — that turned out to be a bit of a non-starter. However, I did track down this lab where they use artificial rumens. ... And they were very kind and sort of, you know, encouraging until I said, "Yes, and then I'm gonna eat the product of this rumen over the space of six days and survive like a goat in the Alps." And suddenly they got extremely worried because they got concerned that I would give myself like a long-term gut, parasitic infection. And that didn't sound like a nice thing to me. ...
I made this kind of bag that I had strapped to my body, and I could take a mouthful of grass and then chew it up and then spit it into this bag. And this bag ... was intended to be my artificial rumen with the goat bacteria in it. But I just really didn't fancy getting diarrhea for the rest of my life so I ended up having to pressure [cook] what I spat into this bag and made a weird delicious, disgusting grass stew.
On thinking like a goat
I had visited a kind of goat behavioral psychologist — an ethologist — and discussed, like, OK, I want to get into the mind of a goat. Because the whole point of the project wasn't ever to kind of make a costume which made me look like a goat; it was like a reverse costume — it was to make a thing that kind of made me feel like a goat. And he said, "Well, we think that goats don't understand language, obviously, and we also think that they don't have episodic memories," that they can't project themselves into the future, you know, and build scenarios or kind of remember specific kind of stories from their past.
So that was my goal, to switch off those parts of my brain. And to do that I had read about this technique called transcranial magnetic stimulation. They get basically a huge, very powerful electromagnet and put it next to your skull. The magnetic field that is generated kind of penetrates into your brain and disrupts the functioning of the synapses in that kind of bit of the brain. I thought, That sounds like a good way of turning off my ability to speak. ...
So there's this particular patch of your cortex which is very important in your ability to speak and [a neuroscientist] put his sort of huge magnet there and switched it on. And, you know, I was reciting this nursery rhyme which I know very well — in fact, "Three Billy Goats Gruff" — and he switched on this magnet and then all of a sudden I just couldn't kind of get the words out.
On how his beard helped him befriend a female goat
One of the things about billy goats is their beard, and they actually try and make their beard as smelly as possible because that's a sort of attractive thing to female goats. And so I think this goat was sort of trying to work out what type of goat was I? ... Weirdly, I think we became friends in the platonic sense. I mean, it's kind of impossible as a human to not tell stories about things. Everything becomes a story, I think, if you're a human, so maybe I'm putting my own vision, my own slant on it. But I did think that, yeah, I've got this connection with this goat.
