Many years ago, the middle-aged Village President (an executive with Johnson & Johnson and a friend of mine) jumped out of the rear seat of a moving car occupied by himself and friends. He survived.
Months later, his wife noticed some liquid of a certain color running out from under the locked bathroom door and called for help. He had done the wrist bit, but survived after a hospital stay.
The third and last time, a year later, and even after lots of counselling, he drove from his suburban home to a deserted Lake Michigan beach near downtown Chicago and walked into the water till his hat floated. They found his body days later miles away.
Three times lucky. Where there's a will there's a way. Suicidals usually don't call talk show hosts if they're deadly serious although there certainly are exceptions to any rule.
Depends. Many people just want help but if they don’t get it in time, suicide starts to look like the only alternative.
