The world makes perfect sense, and that's the problem. People don't like it when random bullshit can take away everything you've ever loved. It's a hard reality to internalize, especially if it happens to them or someone they know. But this solution, to laugh at the inevitable, is a good one I think. Though, like another chatter mentioned, the idea that all laughter fundamentally stems from an anxiety about death is not a very solid idea. Most laughter, I would argue, stems from the unexpected, whether it's dangerous or not. Though I would agree that the strongest laughter is likely laughing at the face of death. But that's just because it's the strongest of the unexpected.
