Why don't we have bunk style bed racks for international flights? I'd gladly take a sedative, crawl into my cubby hole and wake up at my destination 6-12 hours later with no recollection of time loss. Of course, some sort of health screening would be necessary to ride Anesthesiologist Airlines.
Safety first might not be a good rule to guide civilization by. It basically means doing nothing is the best path. Maybe safety third would work better?
