Which of the following is NOT the description of "being alone"? [originaltext]

There is a key difference between being alone and feeling lonely.(18)"Alone" is a state of being by oneself without others around, and can actually be a healthy phenomenon. Everyone needs a little time away from others to plan, consider, and simply to rest. Loneliness is a different matter entirely.
    While it’s normal to feel lonely or isolated from time to time, too much loneliness can be unhealthy or even dangerous.
    The good news is, loneliness is a condition that can be fought against and overcome! For example, you can take a walk. This may seem confusing, but walking has been proven to offer many great health benefits both for the body and the mind.(19)Any form of exercise would do as well, but walking is better because it allows people to explore their town or the area around them in a way a car simply does not allow. While walking, take a different route than you usually would to get to a usual goal point. Even better, simply pick a direction at random and start.(20)Just the feeling of walking down the street, surrounded by traffic and other people, can make you feel more involved in the pulse of your city or town. Besides, you may discover something new you didn’t know your town had to offer!
