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.
The Nicotine, although very similar to Acetylcholine, does not act exactly like the neurotransmitter and consequently causes the systems that it affects to function abnormally. The Nicotine causes a spontaneous release within the brain of other neurotransmitters that affect mood, appetite and memory. Additionally, many systems such as the respiratory and cardiovascular systems are sped up (4). Nicotine causes the pancreas to release glucose, causing smokers to be marginally hyperglycemic.
