I completed the survey, which was extremely long, but found it interesting: could see their direction of travel. I'm always happy to assist with research but like you, had a request to forward it to others and didn't feel I could impose it on anyone else. But if there are people here who are similarly interested in research projects like this, urge you - and your friends - to help University of Cambridge by clicking on the links Happy5 has provided above.
