Biomedical engineering and Star Wars. Driving home: "Mommy I like to build, I want to be an engineer like you and daddy when I grow up, they can build anything" 'They can build anything, you would make a great engineer' "Mommy, well engineers can't build everything can they? They can't build life?" 'Well, God makes life, but engineers can help fix bodies, there are biomedical engineers that can fix bodies when they are hurt in accidents. Like in Star Wars, when Luke loses his hand from Darth Vader, the engineers made him a robot hand to replace it' "Oh, that makes sense mommy"
