No, I think it all evolved, equipment evolved. Dr. Jim McBain, who I worked with for many, many years, was our chief veterinarian. And he always realized that some of the respiration rates on some of the cetaceans seemed to be a little bit higher when we were flying. And so we started talking to some of the pilots, realizing that human beings who get air sick, not everybody gets air sick, but a few people do, what causes them to get air sick is because, if you’re flying at 35,000 feet, the outside air pressure is 35,000 feet. The air pressure inside the airplane is not. It’s about 10,000 feet. And that can cause people to get a little drowsy or a little sick. And what we were realizing, that 10,000 cabin pressure was creating those animals, that are free breathers, you know, they have to exhale, inhale, and it was causing them a little bit to respire a little faster because they needed that exchange.
