Far more worried about at least a dozen other potential health risks in this business. Solar radiation exposure at altitude for cancer, staring at CRTs for vision, loud noise exposure for hearing loss, bad air on the ramp for lungs, terrible sleep patterns, diet choice options, inadequate cooling and darkness in hotel rooms, exposure to the general public by the thousands in planes and terminals, major airports who refuse to install touch less flushing toilets, etc.
A random hydrocarbon going down my gullet doesn’t even ping the radar.
