What are things you do when you're multitasking while driving?

Have an accident, loose you life, kill someone else, and many other very bad things can happen. Driving a car today takes your undivided attention. A car is no place to multitask. Anyone who does this has no business on the road, and is a fool. Amen. The human brain isn't good at multitasking in the "common" sense of the word. And this regardless of any claims made to the contrary. Neurologists are confirming (not finding - they've already found out) that the manner after which the brain functions makes it a "one-thing-at-a-time" kind of machine. What the brain is good at is switching from one task to another. This promotes the illusion that some people are good at multitasking. But, in truth, they really aren't doing "two things at once" as some might think. Texting or doing anything else while driving pulls the attention of the driver from the task of operating the vehicle. It makes driving while texting or some other egregiously foolish thing like that border on criminal. This is being written a week or so after the crash of a commuter passenger train in Southern California where 25 people were killed and over a hundred injured. The train's engineer effectively ran red lights telling him to stop and drove his string of cars into a freight train. He died in the "accident" with some of his passengers, but was texting "a lot" during his run - and up to about 22 seconds before the crash. Better for him (probably) that he was killed in that crash. (Nothing personal here. How would you feel if a family member or loved one was among the fatalities? And would an expensive trial and a long prison term bring anyone back?) This was a train wreck. Something that takes several seconds to develop and to happen. A car wreck happens in the blink of an eye. A link to the news story is below. Use your head on this one. Don't think for a second that you are the "exception to the rule" as regards neuralogical functioning. And don't let anyone else do that, either.

Really is an iceberg a mineral?

An iceberg is a mineral because it has a definite chemical composition, it is an inorganic solid, and it is naturally occurring. You might think it is just frozen water but it is not, it is a mineral when it is an iceberg, but when it melts then it is not a mineral.

Conclusion for alternative communication systems during diasaters?

what is mean by diasaters Natural disasters are often frightening and difficult for us to understand, because we have no control over when and where they happen. What we can control is how prepared we are as communities and governments to deal with the dangers that natural disasters bring.

Places that are more likely to have natural disasters, such as the earthquake-prone Pacific Ring of Fire, or coastal areas vulnerable to hurricanes, require accurate methods of predicting disasters and warning the public quickly. Once the people have been informed, evacuation routes must be provided so that they can all leave quickly and safely, even if they travel by foot. Emergency warnings and evacuation plans are not enough, though. Where there is a high risk of earthquakes, buildings need to be strong and... (more)

Good cell phone?

There are numerous good cell phones on the market as of 2014. Some of the best cell phones are the iPhones, Samsung Galaxy S5, and the Razor.

If you were out of town and when you got back you found a girl's phone number on your boyfriend's cell phone and he said he didn't even know it was there how do you get to the truth?

He could be telling the truth, but if this were to happen again phone the #! Ask who it is, and ask this person why they are calling. Don't accuse them of anything in case it is work related, but if she is seeing your boyfriend she will have great joy in telling you on the phone. Your boyfriend has no control over anyone calling him on his cell, and since he didn't erase the call off his cell phone he doesn't appear he is hiding anything unless he doesn't know how to erase his calls. I think by now he gets the idea that you are onto him. Don't let this one call ruin your relationship because sometimes some people do tell the truth. Just take it slow and easy and keep your eyes and ears wide open. Good luck Marcy

Can you prevent strangers from driving on your driveway?

Yes you can, just by parking your vehicle at the end of the driveway where the strangers are unable to pull their vehicle onto your driveway. Yes, if you build a gate on the inside of your property line and clear of the public property "easement". Of course, that answer is dependant on the local regulations.

If a 25-year-old out of state male sends a 16-year-old female a cell phone can her parents legally take away the phone?

Yes, and they can file a complaint against the adult with the authorities in their state. There are federal and state laws that control relationships between minors and adults; due to the current issues concerning the Internet, those laws are being aggressively enforced.

Is there a program or software that first I would have to download onto computer and then from my computer onto my mobile's phone memory card to program then into the mobile phone for free phone call?

Are you asking for a way to use software to hack your phone in order to make free calls? I'm sure there's a way somewhere, somehow on a very small number of case-specific Mobile devices...

Phone usage is typically monitored remotely-- Your phone is borrowing bandwidth from cell towers, and your phone is clearly identified when it makes a connection to said cell tower. Conning your cell phone provider into giving you a free phone call is hardly worth the effort when you can simply use a free computer phone to make calls instead.

Can you block a number on your cell phone?

It depends on your carrier, but yes, you can. Not from your phone: you will probably have to call your service provider and have an operator/CSR block the number manually. But it is definitely possible.

What is a disadvantage of transmitting information electronically?

  • Power - You need electricity to send and receive the information. If neither the sender nor receiver has the power, the information cannot be properly transmitted.
  • Hacking & Privacy - There is always a chance that the information can be hacked into, stolen or leaked by a deviant individual.
  • Errors - Computers (including phones) are known to have errors and problems, which can affect the content of the information or the transmission itself.
  • Unemployment - As more people begin to trust and use electronic systems, there is less need for the mail service, so the mail service employees lose their jobs.
