I guess I wasn't specific enough with my post, after reading everyone elses posts.
Anecdotally, most of my suicides or attempts are from people that are 50+. Generally they are men. They can be unscientifically categorized in two ways, suicide because of general hopelessness, or "no reason to live anymore", meaning terminal illness or loss of job or something like that.
The "no reason to live anymore's" usually are successful with killing themselves, and dont take anyone with them. They generally leave a note saying that they didnt want to be a burden.
The hopeless ones (depression, family strife, turmoil of some other sort) will often bring everyone with them. These can be more spur of the moment attempts too, going hand in hand with alcoholism or other substance abuse.
All of that is just observation^. My point is I have been seeing this for a while, and feel like its not new. Take that for what its worth.
