I do sometimes wonder how we survived when peanuts were just peanuts and not agents of doom. However, there may have been more casualties of our ignorance then than we were aware of. The fact is that peanuts (and in some cases, all nuts) truly are agents of doom for certain people, and if I were one of those people I wouldn't want to be enclosed in a metal tube 30,000 feet in the air with a peanut-eater no matter how many rows away they were. Also, Epi-pens are more fearsome than most folks realize, and they're certainly not magic. I hope there are other salt-free snacks for you!
