Would you rather know when you are going to die or how you are going to die?

If it were like a car-crash or an accident, I would want to know how, so I could avoid it. Also, if it wasn’t a car crash or anything I would want to know when so I could live up to that day. To cope with knowing that I could die, I would just try not to think about it and spend as much time with my friends and family as possible. I honestly don’t think an accident or anything would be the cause of my death, I believe that it would probably be natural causes, like aging and health-issues would most likely cause it. So, to prevent that from happening to early I will try to stay fit and healthier while I am young, because your youth affects how you (will be) when you are older.
