What are some modern conveniences we take for granted?

There are many conveniences we take for granted in the modern world. People often don't even realize how convenient most of our household appliances, vehicles, and means of communication and entertainment are in our everyday lives. These materials exist to make modern life less stressful in some way, and only without these materials we can acknowledge how convenient they really are. Be thankful for what you have, because one day you may not have it.
