How would you like to have been born without any ability to feel pain? There are such people. One of them is being studied by doctors at a hospital in New York City. He is a 22-year-old clerk who really does not know the meaning of pain. But he wishes he did.
Not long ago a packet of matches flared up(骤然烧起) in his hand. Luckily the burn was not serious. It caused large blisters(水泡)but still did not bother him. He said the burn felt like a fly crawling(在...上爬行) on his fingers. It has been the same story as far back as he can remember. He has never had headaches or sore(疼痛的) muscles. Bee stings, cuts and bruises(疼痛的) do not hurt.
Being free from pain is not as wonderful as you may think. The young man has had to have rotted teeth pulled because he never felt toothache warnings. A sudden attack of appendicitis(阑尾炎) could be deadly. Life without pain is as risky as trying to run a cruise ship without fire alarms.

The transition from old fuels to new will be slow, as will the development of new technologies that present feasible alternatives to fossil fuels or help eliminate food and water problems. All current technologies are inadequate, and new ones will probably not be commercially possible by 2025
