Lucas Meijs, Erasmus University Rotterdam, gave a brief explanation of the research into the effects of 21 years Beautiful as well as in 's-Hertogenbosch. He emphasized two things; almost everything that has been achieved in recent years, is still in the same condition or better to be found and in Mooi Zo Goed Zo the emphasis is not on great things but on activities and services that make people's lives better, more comfortable, warmer and more sustainable and which can pass through each year with little effort (infinity).
