If you watch "Mad Men," the first thing you notice is that everyone smokes and drinks, all day long, even at work. And housewives let their children play with plastic dry-cleaning bags.
Going further back in time, things are even odder. Here are some old photos that depict actual events. The first one shows something unusual -- a "knocker" doing his business. A century ago, people didn't have alarm-clocks so they paid a knocker to walk past their home every morning and knock on their window to wake them up; otherwise they'd be late for work. The other photos are self-explanatory.
Do you remember anything that used to happen that doesn't any more?
