Many people feel anxious about the prospect of their death. Indeed, some philosophers have argued that death anxiety is universal and that this anxiety bounds and organises human existence.

How do weapons inspectors verify that a nuclear bomb has been dismantled? An unsettling answer is: They don't, for the most part.

Instead, past U.S.-Russia arms reduction treaties have called for the destruction of the delivery s
