I work for Sussex Police in one of the control rooms and part of our "patch" contains Beachy Head, well known for suicides etc. If we get more than one call to there in a day it generally is around that phase of the moon. In one new moon period we had three calls to people on the edge in a single day although its more likely to be less than one a week overall. I also remember speaking to Railtrack about a missing person and the staff told me that quite often "one under's" happen around the new moon phase. I tend to believe there is some truth to that saying. Ron
