Life today is easier and more comfortable than it was when your grandparents were children. Science and economy has witnessed unprecedented boom recent years, whole world people are delight with convenience that the science supplied to us. In other words, We have many technologies which our grandparents haven't when they were children. So, In my opinion, life today is easier and more comfortable than grandparent's children. First of all, The transport's vehicle is the most significant change in our life. When my grandfather was young, although it had only 5 kilometer from home to school. He needed to spend about two hours to go by walk. But now, We have many vehicle to choose, like subway、bus and so on, the same trip only take 20 minutes, This vehicles can save our time and power to do other things. we don't need wake up early and worry about what climate today. In addition, remote communication is convenient than past, In 60 years ago, they even not telephone, If my grandparents want to contact someone, they need write a letter and send it, they never know what time they could receive a letter in reply. And now, We can have many tools to contact with our friends or family, like wechat and QQ, what ever they live in.
