Diabetic? Have cucumber juice! Anemic? Sorry I don’t serve liverwurst. Or Fava beans. Or Chianti.
Carrot juice is good for the eyes. That’s why Not-Sees drink it. 🙂
Actually, B12 prevents optical neuropathy. Maybe Germany had a mass B12 deficiency during the Great Depression? That explains why so many did Not-See things. 🙂
