Four years ago an older friend of mine died at the age of 77. I was saddened but not particularly surprised, given his age. Two days later I discovered that he had bee found by a neighbour slumped over the kitchen table with a near-empty bottle of whisky in front of him and a plastic bag over his head. Beside him was a note saying, "Sorry, but I just can't take the pain any more". He was a private person who kept himself very much to himself so no one had a clue as to what had been wrong. I had an inkling as I had last seen him three weeks previously and was struck by how grey, drawn and haggard he looked compared to his usual self yet there was no record of him ever seeking medical help shortly prior to this. Many people are like that; they don't want to be a burden but leave behind a lot of unanswered questions and unnecessary guilt, "... if only we'd known!"
