During the first 10 years after receiving Knowledge, I knew (meaning I have talked to on more than a dozen occasions) five people who commited suicide (including one drug overdose), none of whom were premies.
In the last 20 years, I have known a further 4 people who have committed suicide (including one drug overdose) and one was a lapsed premie.On the other hand I know at least a dozen premies who seriously claim that receiving Knowledge stopped them from continuing on a path that they felt might have led to suicide.
