I'd be willing to choose number 5, yes door number 5! I'd gladly take a robotic body over my useless meat-sack, assuming its the futuristic cybernetics rather than the current clunky stuff. I'd also be willing to augment my brain as well. Not everything, but I'd upgrade the logic, memory, and processing parts of my brain, but keep the emotional and personality sides as untouched as possible. So long as my personality and capacity for emotions are still intact then hell ya, upgrade everything! I will become the next stage in human evolution!!!! NO, I will transcend the weakness of flesh, cast off the squishy shackles AND BECOME MORE THAN HUMAN!!!! I WILL BECOME A GOD!!!! ........ ehem... got a little carried away there.
