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.
Nicotine's mood-altering effects are different by report: in particular it is both a stimulant and a relaxant. First causing a release of glucose from the liver and epinephrine (adrenaline) from the adrenal medulla, it causes stimulation. Users report feelings of relaxation, sharpness, calmness, and alertness.
