32 thoughts on â10 Greatest Empires in the History of Worldâ. 1  For some reason I feel like I need to disagree that the U.S. is not an empire.

How to Safely Clean Your Ears. Normally, ear canals are self-cleaning and should not need to be cleared with any foreign devices. Trying to clean the ear with cotton swabs or other objects can actually cause problems by pushing the ear wax deeper into the ear canal.

Personally, I would never recommend it, but it is safe. However, it would be better to let the earwax do its job. Middle ear infections are an entirely different and unrelated issue.
