Your brain.
Alcohol, even in small amounts, causes irreparable damage to brain cells; some die and others are altered. (this really sounds scary. so i better let go of my that social drinking session that happens even once in a blue moon)

Your heart.
Alcohol incrases the risk of hypertension, stroke, and damage to the heart muscle.

Your lungs.
Alcohol dperesses respiratory functions.

Your reproductive system.
In men, alcohol can damage cells in the testes, causing impotence, sterility, and possibly enlarged breasts.  In women, alcohol can cause irregular menstrual cycles and malfunctioning of the ovaries.  Alcohol has been also linked to birth defects in infants and to fetal alcohol syndrome.

Your liver.
Because your liver must filter alcohol from the blood, alcohol affects it more than any other organ of your body:

• Excess calories in alcohol are stored as fat int he liver.
• Functioning liver cells die from alcoholic poisoning.
• Scar tissue replaces dead cells, causing cirrhosis.

Your immune system.
Alcohol weakens the body’s defence against infection and breast cancer.
