Marley is a businessman. His business is freezing people. He works for a company in California called Trans Time. Trans Time freezes people after they die. Why does Trans Time freeze people? Doctors today can cure many diseases, but they cannot cure all diseases. People still get sick and die. Maybe in the future doctors will have medicine for all diseases. Some people think so. They want Trans Time to freeze their bodies after they die. Maybe 100 or 200, or 300 years later, Trans Time doctors will bring the people back to life. The doctors will cure their diseases, and the people will be alive and healthy again.
People often ask the scientists at the Trans Time, “How will Trans Time bring dead people back to life?” They say, “We can freeze a healthy animal and bring it back to life. We think that someday it will be possible with human.” When they say “someday”, they mean years from now — maybe 100 or 200 years. How can Trans Time keep people frozen for 200 years?
After a person dies, workers at Trans Time cool the body with ice and chemicals. When the body is very cold, workers put the body into a capsule (密封舱). They fill the capsule with liquid nitrogen (液氮). The temperature in it is 196 degrees centigrade below zero. Every two weeks workers add more liquid nitrogen. The liquid nitrogen keeps the bodies frozen.
Trans Time charges $21,000 to freeze a body and $59,000 to keep a body frozen. That’s $80,000 all together. It is a lot of money. But some people think that $80,000 is a fair price. It’s a fair price for a chance to live again, isn’t it?
