The didgeridoo is a musical instrument played by Australian aboriginal people.
Apparently it strengthens the muscles of the throat and pharynx, so that they do not collapse while in a deep sleep.
People can die during a sleep apnoea attack, and some are killed by car accidents caused by day-time drowsiness!
Playin the didgeridoo can save your life!
