Retro Riddles: Can You Guess These Outdated Gizmos?

4. The Ultimate Age Indicator

Look at someone's arm to find out whether they are about your age whenever you ever want to know. They most certainly got the smallpox vaccination about the same period as you if they have a lasting scar! Its unusual form gave the impression that a circular chunk had been removed from your arm, and getting to receive the vaccination was a complete hassle. You most likely even received a sugar cube. Today, the ultimate age indication is this scar. This is so because smallpox was eradicated in the 1980s and so the vaccination was finally phased back out as it was not required.

This little, round scar is a physical timestamp, a remembrance of a worldwide health victory carved on the flesh of a whole generation. Leading to the total elimination of a disease that had dogged humanity for thousands of years, the smallpox vaccination program was among the most effective public health campaigns in history. Often combined with the oral polio vaccination, the sugar cube gives this shared memory still another layer. It's evidence of how public health campaigns changed to make vaccination more pleasant, quite literally, for youngsters. Younger generations lack this scar, which clearly divides medical history and emphasizes the enormous advancement of medical research in one lifetime. For individuals who carry it, the scar represents not just a personal medical history but also a link to an international campaign saving many lives.
