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.
When you smoke a cigarette, you are consuming 1 mg of nicotine, which is enough to produce a stimulating effect on your nervous system. In a small dosage, nicotine boosts mood, improves memory and cognition, decreases appetite, relieves depression, and increases brain activity.
