“It struck him that in moments of crisis one is never fighting against an external enemy, but always against one’s own body... On the battlefield, in the torture chamber, on a sinking ship, the issues that you are fighting for are always forgotten, because the body swells up until it fills the universe, and even when you are not paralysed by fright or screaming with pain, life is a moment-to-moment struggle against hunger or cold or sleeplessness, against a sour stomach or an aching tooth.”
![“I've used the Phoenix Centrifuge to replicate what the body's going to go through on the flight up. I've also done some gravity tests with ZERO-G [a charter-flight service in Arlington, Va., that uses modified Boeing 727s to simulate weightlessness], which went great.” quote by Richard Branson](https://sms4smile.com/quotes/img-quotes/aa1/richard-branson-256_adventure_i-ve-used-the-phoenix-centrifuge-to-repl_903.jpg)
