They pay them back_______________.

B

Some people want to be shot into space after their death, others want to lie deep under the sea. But most people want to go into the freezer(冷藏库).These are believers in cryogenics(低温冷冻学).

Now some diseases can’t be cured, but they may be cured sometime in the future. So some people hope that their bodies can be frozen after they die. When a cure is found, warm up his or her body, bring it back to life and take the cure. Once the body is frozen, it is kept in liquid nitrogen(液态氮) at a temperature of 328 degrees below zero.

Now around a thousand people are going to take cryogenic treatment(处理), though most scientists say it won’t work. If we freeze huge creatures(生物) like humans, every one of their cells(细胞) will be broken. Can they be brought back to life in the future?
