      I imagine your cousin is working on the turbine engines of planes then? If you look at some artificial devices that help the heart to pump blood they’re quite similar to a jet engine! Both use propellers to move fluid. In the heart it’s blood. In an engine it’s air. Look up images of the Debakey Left Ventricular Assist device and Heart Assist 5 🙂
