Patient discussion about declination

Q. what can be the reasons my hearing capability decline? i am 30 years old ... and i'm in great shape , don't have chronic health issues , never had . but recently i found my self "missing" parts while my friends are speaking to me , and it is not just that , i feel like my hearing capability decline rapidly for the last few months , what can it be ? and what should i do ?

A. There are many possible reasons for hearing loss. It can be due to a simple ear-wax plug, that can be easy taken out by a Ear-Nose-Throat specialist. It can also be due to a chronic middle ear infection, or gradual hearing damage due to loud noise. Either way you should see a doctor that can refer you to further evaluation tests.

Voyages undertaken for exploration, settlement, or trade might also produce scientific knowledge as a side effect, as Columbus's first voyage did when he observed magnetic declination (see 1492), or Magellan's when the Magellanic Clouds were observed (see 1678).
