Why is knowing about cells important if you are not going to be a scientist in the future?

The cell is the basic building block of life. All living things are composed of cells, including you! Throughout your life, your body will change in a variety of ways. Some of these changes are normal (caused by aging) and others are not normal (caused by ill health or disease). It is important for you to care for your body and your health. This requires recognizing which changes are normal and which are perhaps a cause for concern. Knowing how your body functions will aide you in understanding your state of health. A deep understanding of your own biology starts with an understanding that you are made of cells.

In summary, it is important for everyone, including non-scientists, to have a basic understanding of cells and human biology because this understanding will help them to lead healthier lives.
