Oh, maaaan, I wish we had it around here: irradiated ground beef! Asuming you follow normal food-prep standards, you can now cook burgers to any done-ness (or lack thereof) you like, with no frets over what the next few hours might bring.
Between that and shelf-storage milk,* there's some mondo-kewl things out there and more on the way, thanks to, you know, Science. And it makes hippies cry! Win. (Money quote: "Whether you're a meat eater, a vegetarian, or waiver somewhere between the two, this renewed push for food irradiation should concern us all." D'ye suppose they sell "vegetarian waivers" at the same counter as carbon credits?)
* Despite which, I still stock and generally prefer powdered milk. It's low-fat, I like the taste and it keeps well-nigh forever. What's not to like?
