We do need to factor in that in most cases real wolrd physics need not apply. Floating island, upside down houses, breathable water. Digimon has had plenty strange areas in the digital world. We just had a temple turn to dust in the wind, and we walked right through a giant tree. So whats to say our blood won't just float away like data when we get injured. In the event of death i see 2 possible outcomes- but that's simply the analytic side of me. Either we simply die succumbing to whatever injuries were inflicted upon us, or we will die in a simialar fashion to Digimon as our whole bodies are data, severe injuries should react like data.

But hopefully we won't have to deal with a dead human.
