Anyone can die because of any reason. But can you believe that many people could die because of dancing? If you don’t believe read below story as mentioned on Wikipedia.
The Dancing Plague (or Dance Epidemic) of 1518 was a case of dancing mania that occurred in Strasbourg, Alsace (then part of the Holy Roman Empire) in July 1518.
Around 400 people took to dancing for days without rest, and, over the period of about one month, some of those affected died of heart attack, stroke, or exhaustion.
The outbreak began in July 1518, when a woman, Mrs. Troffea, began to dance fervently in a street in Strasbourg. This lasted somewhere between four and six days. Within a week, 34 others had joined, and within a month, there were around 400 dancers, predominantly female.
Some of these people eventually died from heart attacks, strokes, or exhaustion. One report indicates that for a period the plague killed around fifteen people per day.
This is considered as one of the unresolved mystery.
