If you are to die in 24hrs what would you do before your heart stops?
Would surf the web, discussing how I feel about dying. With my girlfriend sitting beside me, we're both sipping our favourite drink and laughing nervously, shedding a tear here, a tear there, because we're both too emotional to talk about anything. Perhaps a last kiss, a few parting words, and finally, the last love-making.
Actually I think it'd be too difficult to pray at that point. You're simply over-wrought to think clearly and would make a bad job of praying for the repose of your soul. The best anyone can do would be to find an inner peace in the fact that you know not what the future holds for you and that the things you can make a good or bad job of are the last hours of your existence on this planet that sucks so bad you want to leave.
