❤I've been used to reserving myself. Only by doing this won't I get hurt when I'm leaving.❤
❤No matter what have happened and whether you are ready or not, every next moment is gonna be a brand new start.❤
❤Whatever you do, remember that you do it for yourself, then you will not complain.❤
❤If you get tired one day, you will see my smile as long as you turn around.❤

Unit 7 Technology Around Us - Lesson 1

Lesson 1 Human Limitations

Technology is important in everyday life. Imagine life without technology.

What else can our senses and body allow us to do?
However, there are limitations to what humans can do.

We cannot hear or see things which are tiny, too soft or well-hidden.

We cannot fly or walk very fast or too far without the aid of technology. 

Humans are able to overcome their limitations. Devices are used to overcome the limitations and problems faced by humans.
