The photo on the left shows aging through nature. On one side of the plant, it is flourishing with beautiful cherry blossoms, whereas the right is bare, without any blossoms. It shows that the branch on the right is past its prime, possibly even dead, not producing the beautiful blossoms like the one on the left. The photo on the right shows aging through different styles of mailboxes. The mailbox on the far right is very small and dated; the mailbox in the middle is somewhat old with a funky metal design; the mailbox on the far left is the most modern with a clean and functional look.
