For example: if ((wet && cold) || (poor && hungry)) { System.out.println(I'm miserable!); The println statement will be executed if wet and cold are both true, or if poor and hungry are both true.
Smoking causes depression because of the withdrawal from a physically and psychologically addictive substance, called nicotine. Nicotine which acts as a receptor for the neurotransmitter, acetylcholine, indirectly stimulates the release of another neurotransmitter, dopamine, in the brainâs reward or motivation center.
You may become more anxious, depressed and tired if you quit smoking cold turkey because the nicotine in cigarettes calms you down, brightens your mood and increases your energy level, according to Dr. Dean Ornish's Program for Reversing Heart Disease book.
