What random piece of information do you know that might help others?

Can be anything. Medical, travel tips, computer help, you name it.

My contribution is a medical tip. If you have discomfort in your ear canal and go to the doctor for it, your GP/internist will likely tell you you have no wax when you actually have a lot of wax impacted in your ear canal. It’s beyond me how they are so clueless about this.
