Cholesterol as two forms: HDL (high density; good cholesterol, protects against CHD)
and LDL (low density; bad cholesterol, promotes plaque)

respiration, and increase bodys efficiency in using oxygen

3.Have confidence that they can overcome the addiction
4.View setbacks in overcoming the addiction as temporary and as new coping skills
can be acquired

characteristics of sexual diseases. A portion of the population thinks AIDS can be
casually transmitted
