East Germany, 1990: "No experiments!"

From History of the Present: Essays, Sketches, and Dispatches from Europe in the 1990s, by Timothy Garton Ash (Vintage, 1999), p. 16:

Understandably, the enthusiasm was greatest among the young, while the middle-aged were more worried about their abilities to adapt, and the old were concerned about the conversion rate and the values of their pensions.
