During the process of evolution, electric eels were the first to utilize the properties of electricity to the fullest. It got a stun gun embedded into its tail with an array of biological batteries which it uses as a stun gun against its predator.

Humans were a bit late in finding out about electricity and the way it would empower the world, although ancient alien theorists say that batteries were used even back at the time of the building of the Egyptian pyramids. All the bodies of the lifeforms on this planet work with electrical puleses. The brain sends signals to the bodies in form of electricitcal pulses. If you want to raise your arm, your brain tells the muscles to do it with electrical pulses. All voluntary and involuntary muscles in the body function with electrical pulses.

One very important involuntary muscle in the body is the heart, try telling it to stop, and it wont stop. You have absolutely no control over it. But with age, the pulses that it receives from the brain might weaken, and this is monitored with an ekg machine connected to your body with several electrodes.

But cleaning it is a problem, so it is best to make sure that it doesnt really get dirty by using appropriate hot tub covers to cover it up.

Well, everyone has the right to education, but only until a certain rade at school, where kids learn thebasics. if kids want to go further and specialize themselves, they should assure that they would be able to handle the coursework. And for this they need to take a pre university examination that is called GRE, or the graduate record examination. This exam is to make sure that the universities arent wasting time on students who really dont have the aptitude to learn, and that the clasrooms are filled with only people who really want to learn. Preparing for this exams itself is difficult, and the idea is that even with the huge amounts of gre practice questions out there, if a student isn’t able to do well in the exam, he isnt fit to get into the course that he or she is applying for.
