Do you think Amy Winehouse's death was ctb or an accident?
Chronic suicide, although technically an accident. If she'd been somehow recovered from that episode, she'd have been dead before ever turning 28 anyways. For years, a derisive nickname for her had been Amy "Crackhouse" after her body had withered and it was widely presumed she was deliberately channeling Brian Jones, Janis Joplin, Jimi Hendrix, Jim Morrison and Kurt Cobain by also pushing for a death at age 27. Like them, her death surprised nobody.
Strictly speaking, only Cobain's shotgun death was an intended targeted suicidal act, but he'd almost died of overdoses shortly before multiple times before Courtney Love resuscitated him. (This is why I reject accusations that she was somehow involved in murdering him. He was the father of their daughter and she'd made heroic efforts to keep him alive when she was present to save him. Sure, she was the second coming of Nancy Spungen, but Spungen did not kill Sid Vicious and Love would not have killed Cobain if either of them were to die at the hands of the other.)
These people did not want to live long lives, and were living on the edge as a result, pushing the limits, spurred by the heightening of their own mortality. Joplin probably had to most to live for with her solo album Pearl then under production, but it's generally supposed her tenth high school reunion tore her heart out less than two months before her death after she discovered that her fame and fortune had done nothing to change her social rejection by her former classmates. (Even today, aside from a single bust of her in the Port Arthur library, she is ignored in her home town in favor of the numerous gridiron sports legends who went to high school with her. Gridiron sports, not blues singing, is what has always been revered in Texas. However, Janis remains loved in San Francisco, and her ashes were appropriately scattered from a plane into the Pacific off Stinson beach.)
No, once again, I do not believe Amy Whitehouse deliberately CTB when she died, I think she simply drank to her heart's content, and didn't care if she woke up or not. Because of the potential to vomit, alcohol poisoning is not a reliable way to CTB in a singular binge, only as an extended chronic suicidal act.
Regardless, her chances of living to be 28 were zero, and everybody knew that months before she actually died.
