Snoring

From Wikipedia:
Snoring is the vibration of respiratory structures and the resulting sound, doe to obstructed air movement during breathing while sleeping. The sound may be soft or loud and unpleasant.

Snoring is known to cause sleep deprivation to both the snorer and those who hear him/her.

My Comments:
Only the one sleeping next to us knows whether we snore during our sleep. Snoring is not limited to men, but women and children too.
