[ WP ] A microchip implanted in your head will dictate the percentage probability of death of doing a certain action or task , every second . One day , it starts to say , '' 100 % ''

`` Well, Fi, today I'm going to drive to work.'' It had become habit to consult the chip, the AI, the Fatality Indexer. I'd taken to calling her Fi after a different artificial intelligence I knew which tended to give precise percentages for things that had been just established as extremely probable and obvious. It had stuck, to the point the AI voice had switched to something like hers. 
 
 *Probability of death: 1.2 % * 
 
 `` I can live with that.'' I put my briefcase into the car and started driving. 
 
 I drove past a strip mall with a coffee place I liked. `` Maybe I should stop for coffee here.'' 
 
 *Probability of death: 9.6 % * 
 
 I blinked and did a double take. `` Or... maybe not.'' 
 
 I stopped at the light and heard a crunch behind me. Someone had tried to get out of the parking lot quickly and had misjudged the distance. That could have been me. If I had n't consulted Fi. `` Thank you Fi.'' 
 
 *My pleasure, sir. * 
 
 I was still shaken up by the crash I'd avoided. `` Well, at least I'm going to be safe going to work now.'' 
 
 *Probability of death: 12.2 % * 
 
 `` What? Okay, fine. I'll park at the train station and walk the rest of the way.'' 
 
 *Probability of death: 31.4 % * 
 
 `` Fi, run a diagnostic. That's... not normal.'' 
 
 *Sir, there is nothing wrong and there is no need to run a-* 
 
 `` Run the damn diagnostic,'' I nearly shouted. 
 
 *Very well, sir, * she said, her tone getting snippy. 
 
 `` There's no need for that. I had a scary moment back there and that could be throwing off your readings. I trust you, I'm just... I want to understand.'' 
 
 *Sir, I'm merely using information drawn from your subconscious. You noticed the parking lot had unfamiliar cars in it. Moreover, your office window had the blinds drawn, you did n't do that, and the cleaners do n't come until Thursday. * 
 
 I sighed. `` I have to go to work.'' An idea flickered through my mind. `` Wait, I've got one. What if I do n't go to work today?'' 
 
 *Probability of death: 2.4 % * 
 
 `` What if I go home and stay there for the next week?'' 
 
 *Probability of death: 100 %. Action not recommended. * 
 
 `` Interesting. And if I suddenly go on vacation for a week?'' 
 
 *Probability of death: Unknown. * 
 
 `` By air, to Germany.'' 
 
 *Probability of death: 0.8 % * 
 
 `` By car, to Arizona.'' 
 
 *Probability of death: 0.1 % * 
 
 `` Well, I have n't seen the Grand Canyon.''
