I would have to wonder if it was the Mediterranean diet that lowered the costs or just learning how to cook?
While it's nice to see an article about stir frying, there's a lot of misinformation in this one. I have never even come close to destroying a wok by overheating and I've gotten one of mine to glow before. And, no, no, no non-stick woks!
I love to see things about non-Chinese uses for a wok and this one is particularly well done.
