Want to be an astronaut, but no time for all that pesky training and education? Here's the next best thing: If you are age 24-55 and don't smoke, you can apply to participate in a NASA study of the physical changes an astronaut might encounter during micro-gravity conditions of spaceflight. Currently, a 'Countermeasure and Functional Testing' study in the 'Head-Down Tilt Bed Rest' program called CFT 70,  designed to minimize loss of muscle, bone and cardiovascular function through high intensity aerobic and resistance exercises is recruiting study participants. Seriously! For more information on participating in the CFT 70 program, contact the Johnson Space Center’s Human Test Subject Facility at 1-866-JSC-TEST or visit www.bedreststudy.com.
