When the Italians invented pizza, they just wanted to eat. A humble flatbread with tomatoes and cheese is a snack for workers. With the immigrants it went to the USA, where they added pepperoni, a variety of cheeses, sausages, eggs, vegetables and a side of cheese, a box, the slogan "hot and ready" and turned pizza into a global fast food. Scientists call this the "pizza effect" - when something local goes abroad, it gets an upgrade and returns home as a star. Yoga left India as a spiritual practice and returned as fitness for those who wear leggings and believe that "the chakra is a muscle". The sushi fled Japan as a block of rice with raw fish - and returned in a sweet "spicy" sauce, with avocado and Philadelphia cheese. The espresso left Rome with a thimble (well, they didn't make bigger cups in Italy!), and flew back from Seattle in a bucket with a caramel coating and the name "latte". Even Mexican tacos, having survived their childhood in Texas, now return home under the proud banner of "Tex-Mex style" with nachos - which never existed in Mexico. But the most interesting thing is that the creator country says: "Well, if you like it that way, then that's the way it's always been. Italy today proudly markets American pizza as an "old Italian classic". The Indian studios offer western versions of yoga "for the truly enlightened". In Japan you can buy "real California rolls from sushi masters". And everyone pretends that this is exactly how it was intended from the beginning.
