Life past and now
In the past, people's lives were more difficult because it was not enough technology and invention; there are a lot of them now, so we can feel good when we do something. For example, we can geel good when we cook dinner. Old people needed to start making the fire before they cooked dinner. Also, there was no clean water.
We can take some medicine whenever we are ill, but they could not take it and go to the doctor everytime. That's why they fought with illness by themselves, but humans could not overcome it without medicine.
We have cell phones, so we can speak to people who live in another city or county, but they could not speak with them. In my opinion, they were very sad when they would liked to speak with them.
Finally, we needed to increase quality of life because people's lives were diffficult in the past.
