The refrigerator has impacted our lives in multiple ways. It is the best way to keep our food fresh and cool. It is also a good way to make our food last a lot longer so we don't have to waste the food we don't use within a couple of days. We are very lucky to live in a time where we don't have to do too much work in order to keep our food fresh, cool, and that will last longer.
