A person might have some clothes that are 5-10 years old, but kept them in good condition by not wearing them that much. A person might have an extra TV that's closer to a decade old than 5 years old, but it still does what it was meant to do. A 10 year old car can still work well, provided that its been properly maintained. A 5 year old smartphone or a laptop can still work, but it will seem a little old. However, some people might not only like to have a car that's more than half a decade old, but a laptop as well.
