Learning that listening to something with headphones for an hour increased the bacteria in the ear by seven hundred percent, I can say that it was the most unnecessary information I knew. What was the need for this information? I could live without this knowledge. In fact, I would probably have lived happier. Every time I use my headset, it comes to my mind and I feel uncomfortable.

One of the most unnecessary information I learned is the method of making my jacket a pillow that I use when I have an uncomfortable sleep while traveling. I can make my journey more comfortable by making a very different and comfortable pillow, but in general, it is quite unnecessary information.
