Here are some interesting data points:
Top 5 causes of death overall (US, 2002)
Heart Disease (696,947)
Malignant Neoplasms (557,271)
Cerebrovascular (162,672)
Chronic Low Respiratory Disease (124,816)
Unintentional Injury (106,742)
Top 5 causes of death ages 25-34 (US, 2002)
Unintentional Injury (15,412)
Suicide (5,219)
Homicide (4,489)
Malignant Neoplasms (3,872)

Top 6 causes of death by years of potential life before age 65 (US, 2002)
Unintentional Injury (2,159,266)

Heart Disease (1,434,511)

Homicide (579,268)
Over 50% (1,166,780) of the years lost due to Unintentional Injury are due to motor vehicle injuries. If we counted it as a separate category it alone would be the third leading cause of death. Drive carefully, folks.

People have to die somehow...
