People who are in their twenties have  plenty energy and stamina for partying, but they may not realize the long term effects.  The damage that smoking can do to the lungs is widely known, but less often considered is the permanent damage that can be done to the hearing after repeated exposure to loud music.  Alcohol can affect both the organs and the mind, causing an irregular heart rate and a lack of coordination and balance.  After a party, the liver is called upon to convert poisons like alcohol into harmless chemicals.  To do this, the liver sucks water and essential salts from elsewhere in the body – especially the brain.  This is the source of a hangover headache.
