Being in space is like being at a really high altitude? Idiot author.
The atmosphere of the ISS is maintained to approximately 760 mmHg (14.7 psi), with 78% nitrogen and 21% oxygen. The remaining 1% is composed of metabolic products such as carbon dioxide. Humidity is kept between 40-70%."
I seriously doubt sea level pressure is maintained in space vehicles.
Airliners maintain 8,000 ft pressure altitude when at cruise, space capsules are not pressurized to that level, a quick search should find the normal pressures in the space station.
While poorly worded, the author is correct.
