如果你從別的地方來，我大概得先說明：真正的肉、蛋、米，現在已經很少出現在一般人的餐桌上，我們的蛋白質大多來自角蛋白，也就是頭髮、羽毛、羊毛這些東西。在這裡，沒有人覺得這件事特別，就像你們不會特別去想米是從哪裡來的。我只是把每天看到的東西記下來，也許透過這些日常，你會比較容易想像我們是怎麼生活的。

If you come from somewhere else, I should probably explain first: real meat, eggs and rice rarely appear on ordinary tables anymore. Most of our protein comes from keratin, from things like hair, feathers and wool. Here, nobody thinks this is remarkable, just as you probably never stop to think about where your rice comes from. I am simply writing down what I see each day. Perhaps through these everyday things, it will be easier for you to imagine how we live.
