A Quote by Chris Hadfield

Other anatomical changes associated with long-duration space flight are definitely negative: the immune system weakens, the heart shrinks because it doesn't have to strain against gravity, eyesight tends to degrade, sometimes markedly (no one's exactly sure why yet). The spine lengthens as the little sacs of fluid between the vertebrae expand, and bone mass decreases as the body sheds calcium. Without gravity, we don't need muscle and bone mass to support our own weight, which is what makes life in space so much fun but also so inherently bad for the human body, long-term.

People do really well on space missions, but it's the physiological, the medical stuff, the stuff like radiation, loss of bone mass and muscle mass and density. It's those things that we need to figure out.

Scott Kelly

What I'm against is a sport that rewards mass for the sake of mass to the exclusion of all other physical properties of the physique. In other words, there comes a point where, if you keep adding muscle mass, the human body loses its beauty, shape and form. That's what I'm against.

Lee Labrada

Young women should begin to build bone mass early in their lives. The more mass there is, the less they will lose in later life. They should enjoy a diet of calcium-rich foods and avoid food and drink that causes bone loss.

Ann Richards

During our journey, we did weight lifting, squats, and dead lifts to regenerate the bone density. Luckily, my muscle mass and bone density did not alter. Our workout was so rigorous.

Sunita Williams

With no gravitational force to work against, your body not only doesn't need the same amount of muscle and bone, it starts breaking them down. As on Earth, so in space: use it or lose it. And exercise may not solve the problem.

Neil deGrasse Tyson

We were doing something called telemedicine, where we were using the ultrasound. One interesting application of this ultrasound is the possibility that you could possibly use it to measure critical bone areas during a long space mission and track if you're losing bone in these areas. On Earth, when they check you for bone loss, you get in this big machine. It's the size of a room and it's got a platform with an x-ray that scans your whole body and in critical areas and it takes a while and it just wouldn't be practical to have a machine like that in space.

Leroy Chiao

While you're in space, you grow in height! Without the constant force of gravity on your spine, it stretches out, and you're actually taller when you land. It doesn't last long though.

Christina Koch

One of the things I found as a dancer is that you're trying to perfect your body but also protect it and keep it injury-free. When you work against your own weight, you're still building lean muscle and bone density, but you're in a safer zone.

Mary Helen Bowers

For some, a perfect body means having muscle mass and fat in proportion to one's height. For others, it may mean more than just muscle mass and body fat. For me, it's also about having amazing features.

Sherlyn Chopra

Leg day is my favorite day. You can't have a thorough leg workout without feeling completely spent. It's a challenge, but the benefits of maintain muscle mass on my legs is important because, as the biggest muscle group in the body, it also helps me keep the proper body composition in terms of fat to muscle ratio.

Ian Ziering

Life as an astronaut in space is a very interesting one. There are things we all take for granted here on earth, like gravity, that can make things a bit challenging. One of the fun things about getting here is the zero gravity and floating around. But it also makes things very difficult.

Kevin A. Ford

Space, time, mass, and energy originate from Chaos, have their being in Chaos, and through the agency of the aether are moved by Chaos into the multiple forms of existence. Some of the various densities of the aether have only a partial or probablistic differentiation into existence, and are somewhat indeterminate in space and time. In the same way that mass exists as a curvature in space-time, extending with a gradually diminishing force to infinity that we recognize as gravity, so do all events, particularly events involving the human mind, send ripples through all creation.

Peter J. Carroll

The whole mass of any body is just the mass of ether surrounding the body which is carried along by the Faraday tubes associated with the atoms of the body. In fact, all mass is mass of the ether; all momentum, momentum of the ether; and all kinetic energy, kinetic energy of the ether, This view, it should be said, requires the density of the ether to be immensely greater than that of any known substance.

Joseph John Thomson

We as women know that there are no disembodied processes; that all history originates in human flesh; that all oppression is inflicted by the body of one against the body of another; that all social change is built on the bone and muscle, and out of the flesh and blood, of human creators.

Andrea Dworkin

There are some very significant changes in the way the fluids are distributed in our body, the way our heart functions initially, and as well as our bone and muscle.

Laurel Clark

Two hundred miles from the surface of the earth there is no gravity. The laws of motion are suspended. You could turn somersaults slowly slowly, weight into weightlessness, nowhere to fall. As you lay on your back paddling in space you might notice your feet had fled your head. You are stretching slowly slowly, getting longer, your joints are slipping away from their usual places. There is no connection between your shoulder and your arm. You will break up bone by bone, fractured from who you are, drifting away now, the centre cannot hold.

Jeanette Winterson
