Real rocket tech is fairly complex. You have to pump fuel and 02 in without it exploding. Nothing seems quite as dangerous as having tanks of hydrogen and oxygen sitting around, on a flying stick no less. The engines themselves are actively cooled by the fuel, mainly the nozzle, and failure to cool this properly leads to fuel leaks and well, a bang. They also must be able to survive extreme forces and vibration, and the very wide ranges in temperature. They must also be reliable enough to use multiple times between inspections for some missions.

Brain surgery is incredibly complex. Honestly I have no idea which one is harder because I do neither. I think medical people don't get as much respect because there are so many of them.
