It’s winter in the Northern Hemisphere, and your skin is blotchy, your mind is addled, your teeth are falling out, you have crackling joints and rheumy eyeballs that won’t point straight.
You need many things. But thankfully you can get some of them by trapping a bunch of fish in a net, sucking them into a big steel ship hundreds of miles from land in treacherous seas, cutting out their livers and then feasting on the gloopy fish-stinkin’ juices until the first salad of springtime. By which time you’ll be near transparent, skeletal and flabby all at the same time.
