if I had only 1 day to live

If I had only one day to live, then I would just live like a normal life with normal schedule, because I like the way I'm living right now. But if I can what I would like to do, then I would like to be dead in a coffin, not somewhere else, or bed because then it might freak somebody out,(I don't want a companion) and I would like to do whatever I can on the computer, and I would like for my brother to survive. (I don't want to see him as soon as I go to heaven, then I would have the same life as in Earth) And I wish I don't die.
