Today is supposed to be a day to build our self-esteem. A day to look in the mirror and—whether we are young and old, male or female, sick or healthy—assure ourselves, “You look fabulous!”

We have one-way mirrors that enable, for example, police to watch suspects in an interrogation room while the suspects cannot see them.
There are lots of other uses for mirrors, as well—everything from military uses to emergency signaling uses, uses in everything from seasonal lighting and “green” skylights to TVs and cameras.
What did people use as mirrors way-back-when?
Glass mirrors with metal backing date back to the first century C.E. or earlier. However, for a good long while only rich people were able to afford good metal-backed glass mirrors. (The silvered-glass mirrors we use today was invented by Justus von Liebig in 1835.)
People also sought their reflections in highly polished metal or obsidian mirrors—and, of course, in very still water.
