Only the ones you could ask afterwards;) This is propaganda pretending that suicide is an impulsive decision. That's a category error because in many cases, it is not.

If there was more focus on screening for impulsive thoughts and disrupting people who suddenly change behaviour, modern suicide prevention would do much better. The people who really want to die do not engage with therapy or mental health services because they know they'll be having their freedom taken away if they mention their thoughts to anyone else. That's why many of these stories go like "oh he looked so happy! no one could have known" - yeah because he was smart enough not to say anything;)
