First, the past 50 years sees the changes in our food. In the 1950s, our grandparents did not have enough food to eat and sometimes they had to stand with hungry. However, today in a supermarket we can get enough food that we need. Even although some of us don't have enough money to buy it, governments will always aid you. Thus we don't worry about hungry. In addition to enough quantity of food, we also have a large variety of food. For example, we can find food such as the fruits from American in our market, which is hard to image to our grandparents.
Second, another change in our life is that transportation becomes easier. I remember my grandfather has told me that when he was a student, he had to walk 10 km to go to his high school, because few people had a bicycle, not mention a car. However, the situation has changed now. If you want to go somewhere in a city, we have many choices such as a car or a bus, and they are very fast. Although we might be stuck in a traffic jam, in generally, it is still faster than using feet. Besides, the development of train and airplane also make the long-distance trip easier than the past. For example, in the past, most people would choice a ship as they went to American; it would cost them several months. Today we can finish the trip by airplane in only one day.
