1. In ways that are easy to overlook and yet are so impacting, your reputation will cause your present or potential relationships to be affected, and almost always adversely. You may fall in love with a person who won't have anything to do with you because of your past deeds. You may want to raise your children to respect the law and authority, yet they won't
acknowledge your authority because of your doing such a knock-out job of rebelling against it previously. You may come to a place where your family members want nothing more to do with you because their own reputations have been burnt too many times by who you are in the eyes of the common man. No matter who you want to be in life presently, you should always consider who you want to be in the future. You want to evaluate the "what-ifs" that may come about. Prudence is the type of wisdom that foresees future things that could come to pass based on your choices. So whether you are the die-hard who wants to have a reputation as such, or whether you are the model citizen, it's prudent to evaluate your aspirations and where they could take you in life.

We all depend on electricity. Most electricity is created by electromagnetic generators at large power plants and distributed through an electric grid. The electric grid in the United States is interconnected and includes more than 400,000 miles of electric transmission lines. However, the grid has not been well maintained, and the number and severity of power outages has been rising over the past decade. Because the grid is interconnected, a severe power outage in one area can quickly spread to other areas.

How long could you survive without electricity? What parts of your life would be affected by loss of electricity? Should you prepare for an electricity outage, and if so, how would you prepare? What backup system could your family or community install to generate limited amounts of electricity during an outage? How does this system create an electric force field and generate electric current?

Answers

I couldn’t survive without electricity sorry

Answer:

You should be able to survive without electricity, unless there is unbearable weather that leads to death (such as freezing)

The loss of electricity will mainly affect ones social life because they can't use any devices (or they will at least die at some point and no internet)

You can get a generator

Generators don't actually create electricity. Instead, they convert mechanical or chemical energy into electrical energy. They do this by capturing the power of motion and turning it into electrical energy by forcing electrons from the external source through an electrical circuit.
