Long ago, operation usually had to be done while the sick man could feel everything. The sick man had to be held down on a table by force while the doctors did their best to save him. He could feel all the pain if his leg or arm was being cut off, and his fearful cries filled the room and the hearts of those who watched.
Soon after 1770, Josept Priestley discovered a gas which is now called “laughing gas”. Laughing gas became known in America. Young men and women went to parties to try it. Most of them spent their time laughing, but one man at a party, Horace Wells, noticed that people didn’t seem to feel pain when they were using this gas. He decided to make an experiment on himself．He asked a friend to help him．
Wells took some of the gas, and his friend pulled out one of Wells’ teeth. Wells felt no pain at all.
As he didn’t know enough about laughing gas, he gave a man less gas than he should have. The man cried out with pain when his tooth was being pulled out.
Wells tried again, but this time he gave too much of the gas, and the man died. Wells never forgot this terrible event.

Now I know that we black people are much more likely to have high blood pressure and diabetes(糖尿病) than white people. And they often lead to heart attacks and other untreated diseases. For example, black people are three to four times more likely than white people to have high blood pressure and twice as likely as the white population to die of a stroke(中风).
New research has found out the surprisingly high levels of salt in many of black people’s favorite meals. I stopped putting extra salt in my food at the table long ago and I try to cut down on the salt I use in cooking. The recommended daily level of salt for adults is 6 grams. It is easy to see that if you avoid processed(加工过的) foods and use salt in your cooking within the limit, you won’t exceed the daily level.
The research showed how much salt there is in some foods that we buy from restaurants and takeaways. An average salad with rice and peas has 6.2 grams of salt. This is more salt than you are supposed to eat for the whole day.
A researcher talked about the importance of home cooking rather than take-outs. At home, he pointed out, not only can you hold control of the salt shaker, but also you can create tasty food which is low on salt. The researcher later provided curry goat and rice and peas. They were low on salt, but completely delicious.
I do not suppose Jamaicans are going to stop buying takeaways soon. But if you suffer from high blood pressure, it is probably better not to buy them often.
