Time is an odd concept. With enough time, everything changes in some way or another. Time affects everyone and everything, it can be a thief, sometimes. Time takes a toll on every aspect of life, regardless of whether it is living or not. Sometimes things change so slowly and in such minor ways that no one even realizes it until the thing is too far gone. The changes are small, and they are only noticed when compared to the new product. This is both eye-opening and interesting to see how everything changes with time and how different new and old products can be.

These kinds of comparisons might inspire someone to look closer at their environment to see how it has been used.
