Two questions which arises in my mind about aurora borealis are:
- Why does aurora borealis occur?
- Why does aurora borealis occur in a particular time of the year?
Answers:
- As solar wind approaches the Earth, it meets the Earth's magnetic field. In the ionosphere, the ions of the solar wind collide with atoms of oxygen and nitrogen from the Earth's atmosphere. The energy released during these collisions causes aurora borealis.
- Aurora borealis is active the whole year. Since it needs to be dark in order to see aurora borealis in the sky, late August/September through the very beginning of April is the best time to go to a destination located in the aurora zone for a chance to see them.
Note: These are the questions which arises in my mind only. It may differ from person to person.

The baby-boom generation is a generation that has had much different lifestyle than the previous generation, or rather the generation of their parents. The rights of the men and women have become equal, as well as the earnings. The marriage has been delayed for later stages of life, also having less children, and relatively high divorce rates.
On the long run, this generation will have a negative demographic impact on the United States. The reason for that is that the birthrates of this generation have dropped significantly, and it is also representing a large portion of the population, so as they age they will contribute to aging population.
An aging population can have serious economic and social impact, as the percentage of people that take money from the pension funds will increase significantly relative to the people that work. Also, as the baby-boomers age, the healthcare will be overrun by them, as deep age and diseases often goes hand to hand, so the expenses for the healthcare will be enormous.
