Legendary you say? Relatively unknown outside of Germany (and other German speaking countries) you say?
Let me introduce you to Dschinghis Khan by Dschingis Khan
(99 Luftballons, which was mentioned here before, is arguably the bigger hit that really everyone knows. But I couldn’t resist throwing this out there. It was a huge hit and is still known.)
I don’t think I do know actually. But here’s an attempt at answering this question anyway:
We are usually very quick at relating sickness or even discomfort to the food we ate at the time or slightly before. This is a very valuable trait to avoid food that is unhealthy or even poisonous. But it’s only based on correlation, so it can turn us off food that is not actually causing the sickness but we just happened to eat at the time.
