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.
It comes as a patch, gum, inhaler, or nasal spray. Nicotine is also being studied for helping other neurological conditions such as Parkinson's disease, schizophrenia, mild cognitive impairment, and Tourette's syndrome. Some research has suggested that the drug may also improve attention and symptoms of depression.
