The idea had come to me as I listened to a talk on my car radio.The speaker was quoting a Biblical (圣经的) passage about husbands being thoughtful of heir wives.Then he went on to say, “Love is an act of will.A person can choose to love.” To myself, I had to admit that I had been a selfish husband.Well, for two weeks that would change.

And it did.Right from the moment I kissed Evelyn at the door and said, “That new yellow sweater looks great on you.”

“Oh, Tom, you noticed,” she said, surprised and pleased.Maybe a little puzzled.

After the long drive, I wanted to sit and read.Evelyn suggested a walk on the beach.I started to refuse, but then I thought, “Evelyn’s been alone here with the kids all week and now she wants to be alone with me.” We walked on the beach while the children flew their kites.

So it went.Two weeks of not calling the Wall Street firm where I am a director; a visit to the shell museum though I usually hate museums.Relaxed and happy, that’s how the whole vacation passed.I made a new pledge to keep on remembering to choose love.

There was one thing that went wrong with my experiment, however.Evelyn and I still laugh about it today.On the last night at our cottage, preparing for bed, Evelyn stared at me with the saddest expression.

“What’s the matter？” I asked her.

“Tom,” she said in a voice filled with distress, “do you know something I don’t？”

“What do you mean？”

“Well… that checkup (体检) I had several weeks ago … our doctor… did he tell you something about me？ Tom, you’ve been so good to me… am I dying？”

It took a moment for it all to sink in.then I burst out laughing.

“No, honey,” I said, wrapping her in my arms.“You’re not dying; I’m just starting to live.”

On earth gravity (引力) makes blood flow down towards the feet, so the heart must work to pump blood up. In space blood flows up towards the heart. The effect is similar to what happens when you lie with your feet up and your head down. The flowing blood is felt by receptors in the walls of arteries (动脉) in the upper part of the body and in the heart. These receptors send signals to the brain, but the brain reads them incorrectly. To the brain, the signals means the amount of blood in the body has increased, so the brain tells other parts of the body to react to the increase in the blood. For example, the body produces more urine (尿液), resulting in loss of body fluid and salt. At the same time the astronaut has less desire to drink and so does not replace the lost fluid.

As a spacecraft begins to fall back to earth atmosphere, the crew begins to feel gravity. Blood again flows towards the feet and collects there. The heart beats faster in an effort to pump enough blood to the brain. Some crew members may not get enough blood to the brain and the heart beats too fast. They become sick and even lose consciousness as their spacecraft reenters the earth atmosphere. To prevent this, special clothing is invited for astronauts to prevent blood collecting in their legs. They put it on just before the craft reenters the earth’s atmosphere. They also drink about a liter (升) of water and eat some salt to replace the fluid they have lost while in space.

Weightlessness affects the heart and blood vessels in another way. The heart does not work as hard in a weightless environment as it does in an environment of gravity. When the heart works less hard, the heart muscles become weaker. It is replaced by fibrous tissue and fat
