Chris Hadfield Quotes

Gravity on Earth provides a force that keeps our bones and muscles working. In the microgravity of space, our bones and muscles are not taxed, so they begin to atrophy.

The bodies we have are not made for extended use. We must cope with accumulated DNA damage, cell damage, muscle atrophy, bone loss, decreased muscle mass, and joints worn out from overuse during a lifetime of bipedal locomotion. It might have worked great for prehistoric humans, but it wreaks havoc on our knees and hips.

The microgravity or the very, very low amount of gravity that we have up in space forces some changes in different processes. It forces changes in us as human beings.

Here we have a baby. It is composed of a bald head and a pair of lungs.

When you're under stress, your immune system doesn't work as well.

Tobacco smoke contains chemicals that weaken the body's immune system, making it more susceptible to disease and handicapping its ability to destroy cancer cells.

As the spinal cord increases, it makes you taller. However, after landing on the Earth, you shrink a bit. What was worrisome was that some of the wrinkles, which had disappeared there, came back.

One thing we've learned about space is that the human body starts to fall apart after relatively short exposures to microgravity.

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.

Cults and prophets proclaiming the imminent end of the world have been with us for several millennia, and it has been another sour sort of fun to ridicule them the morning after, when they discover that their calculations were a little off. But, just as with Marxists, there are some among them who are working hard to "hasten the inevitable," not merely anticipating the End Days with joy in their hearts, but taking political action to bring about the conditions they think are the prerequisites for that occasion.

Clearly, there is some invisible force that is moving every aspect of reality to its next best expression. And the universe is not only self-organizing, it is also self-correcting. The embryo becomes a baby; the baby is born; its lungs continue to breathe - not only were they created but then they continue to breathe. The heart is not only created but it continues to breathe. If there is injury and disease that becomes present within the body, the body is also equipped with an immune system to correct that.

We are the ones who have high blood pressure, ulcers, and heart attacks, not cats.

I think I went through puberty. I'm, like, 20 now and I was, like, 17 then, ... You know, I've experienced different things and am having a lot more fun with it.

With 'The Office' and 'Extras' I've always snuck in a little bit of heart and pathos - and drama, which is fun.

The TV show I do ['Dr Quinn'] is the day job that enables me to work with this theater [Pacific Resident Theatre Ensemble]. That's all I live for. That's what I care about. There's no dough in it. Nothing to do but lose money. But it's all from the heart, and that's why it's so much fun.

Even the village rain-maker no longer claimed to be able to intervene. He could not stop the rain now, just as he would not attempt to start it in the heart of the dry season, without serious danger to his own health.

A good leg will fall; a straight back will stoop; a black beard will turn white; a curl'd pate will grow bald; a fair face will wither; a full eye will wax hollow: but a good heart, Kate, is the sun and the moon; or, rather, the sun, and not the moon, — for it shines bright, and never changes, but keeps his course truly.

Exercise is very important, first of all if you think about it, especially in a long flight like a six month space flight and on the ISS. If you didn't exercise and used the analogy on earth, it would be like laying in bed. So, just imagine laying in bed for several months, and even just trying to get up and walk, you probably wouldn't be able to. But if you got up and you exercised two hours a day, you'd probably be okay, and that's the same in space.

Your heart is my piñata.

On May 7, a few weeks after the accident at Three-Mile Island, I was in Washington. I was there to refute some of that propaganda that Ralph Nader, Jane Fonda and their kind are spewing to the news media in their attempt to frighten people away from nuclear power. I am 71 years old, and I was working 20 hours a day. The strain was too much. The next day, I suffered a heart attack. You might say that I was the only one whose health was affected by that reactor near Harrisburg. No, that would be wrong. It was not the reactor. It was Jane Fonda. Reactors are not dangerous.

Sometimes I write music, sometimes I don't. I think I'm just writing more what's close to my heart, and musical stuff is close to my heart, and it's fun to write, and when something's fun to write you don't think about what statement you're trying to make or what genre you're trying to hone in on.

Slowly, very slowly, he sat up, and as he did so he felt more alive, and more aware of his own living body than ever before. Why had he never appreciated what a miracle he was, brain and nerve and bounding heart? It would all be gone...or at least, he would be gone from it. His breath came slow and deep, and his mouth and throat were completely dry, but so were his eyes.

My heart is really pounding," I said. "That's how you know you're having fun," Margo said.

Smoking is, if not my life, then at least my hobby. I love to smoke. Smoking is fun. Smoking is cool. Smoking is, as far as I am concerned, the entire point of being an adult.
