Isn't It Time to Rethink?

Suc, it's a space that we can to learn from and build from. I lav sam'se idea that new problems do not need new solutions because powerful ideas have already been solved in biology, technology and psychology. We see this ourselves in the world of applied paper science. Sometimes the smallest things, like changing the weight of an envelope, the greatest impact in changing behavior. Until next time, good bye, nudgers.
