Body Quote by Ken Shamrock
“No matter how tough you are or how much willpower or determination you have, if there's something wrong with your body, it's going to shut down and stop. It's good to have those qualities, but it's important to know what you're pushing against.”
![“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)
