Which Death Would You Choose? [Survey]

Suppose you know your death is imminent, but you have a choice about how you will die. What would you choose? We’ve been mulling over this question ever since our friend Tim Taylor posed three possible scenarios. In each case, the process would begin soon, not decades in the future when you might be old and frail. 

Choose one of the three choices below, and please share why you chose this particular way to die. You can read other people's submissions in their raw form, and read through some early analysis of answers.

Please tell us why you chose the answer you did.
