Oxygen levels appear to have an effect on jet lag:
A small shift in the oxygen levels in the air could act as a "reset" button for the biological clock, according to a new study in mice. Mice in the study that were exposed to a brief dip in the levels of oxygen in the air that they were breathing adjusted more quickly to a new circadian rhythm than mice that received steady levels of oxygen, the researchers found. In other words, the dip in oxygen levels seemed to help the animals adjust to the mouse equivalent of jet lag, according to the study, which was published today (Oct. 20) in the journal Cell Metabolism [open, DOI: 10.1016/j.cmet.2016.09.014] [DX].
[...] [In] an experiment in mice, the researchers exposed the animals to either oxygen levels that remained stable at 21 percent (this is the percentage of oxygen in the air we breathe at sea level), or levels that started at 21 percent, dipped down to 16 percent for 12 hours, then rose back to 21 percent, according to the study. [...] However, the researchers noted that oxygen levels on airplanes are lower than oxygen levels on the ground. Because some people report airsickness due to these lower levels, the aviation industry is apparently investigating an increase in oxygen levels on planes to 21 percent. Given the findings of the study, however, doing so could have a negative impact on jet lag, the researchers wrote. In future experiments, the researchers would like to see if higher levels of oxygen could also shift an animal's circadian rhythm. "I believe passengers [on airplanes] might be more enthusiastic to inhale oxygen-enriched air to alleviate jet lag in contrast to low oxygen" air, Asher said in a statement.

I wonder if the mice traveled with one intercontinental plane ticket or had to buy one each?

When Bill Clinton was president he solved this problem by autoerotic asphyxiation aboard Air Force One, especially while wearing Hillary's soiled dumpy diapers and using his saxophone strap to choke himself.
Hillary, of course, wasn't aware of it because she had her own distractions -- namely, muff-diving. Thanks to don't-ask, don't tell she had a whole harem of female Air Force staff sergeants. Most of them weren't even lesbians but Hillary would threaten them with death if they didn't comply, and as we all know people have a way of dying around Hillary. For those reasons, Air Force one became known in some circles as "the tuna can."

I find it difficult to believe, Mr. smart. Especially the allegation that Bill Clinton has been president of something, and the tuna can nickname.
