Compare than to just 10 people over 100 years for every 100,000 Americans. Scientists have studied the Okinawans and attribute their long lives to hard work, clean air, and diet—which, you guessed it, includes a lot of seaweed. The Okinawans, like many Japanese and Asians, love their seaweed, and eat it as part of many meals. The Japanese, overall, live longer than any other people on earth, with an average lifespan of 79.4 years for men and 86.5 years for women? And among the Japanese, the Okinawans live the longest. Mahinda Seneviratne and Soo-Hyun Kim, report that it showed “significant activities in all antioxidant assays...activities that were superior to those of a commercial synthetic and natural antioxidant tests.” Scientific research also documents that Ecklonia cava has shown “higher scavenging activities” toward free radicals, as this  “super antioxidant” penetrates your cells more effectively.

One-sentence summary -- In a study for every 100,000 Islanders living on Okinawa, there are 457 people over 100 years old.

Q: To calculate the normal force of an object at an angle, you need to use the formula: N = m * g * cos(x)  For this equation, N refers to the normal force, m refers to the object's mass, g refers to the acceleration of gravity, and x refers to the angle of incline.  Example: Find the normal force of a block with a mass of 4.2 kg, sitting on a ramp with an incline of 45 degrees. The cosign of an angle equals the sine of the complementary angle, or the adjacent side divided by the hypotenuse of the triangle formed by the incline.  This value is often determined by a calculator, since the cosine of any angle is constant to that angle, but you can compute it manually, as well.  Example: cos (45) = 0.71 The weight of an object equals the mass of the object multiplied by the acceleration of gravity.  Note that the gravitational acceleration at the Earth's surface is a constant: g = 9.8 m/s2   Example: weight = m * g = 4.2 * 9.8 = 41.16 In order to find the normal force, you need to multiply the weight of the object by the cosine of the angle of incline.  Example: N = m * g * cos(x) = 41.16 * 0.71 = 29.1 The previous step should complete the problem and give you your answer.  Note that for an object sitting on an incline, the normal force should be less than the weight of the object.  Example: The normal force is 29.1 N.
A: Use the right equation. Find the cosine of the angle. Find the object's weight. Multiply the two values together. Write your answer.

Article: Mortar and pestles are usually made in a matching set. The mortar is a small bowl and the pestle is a wand with a curve that's perfectly shaped to grind smoothly against the mortar. The instrument may be made from wood, stone or ceramic, and you'll want to choose your material based on your culinary needs and personal preferences.  Ceramic mortar and pestles are capable of grinding spices very finely, but they're also more fragile than other types.  Wood mortar and pestles are durable, but they're also slightly porous, and subject to stains. It's also possible for the flavor of one spice to stay present in the mortar between uses, tainting the flavor of the next spice you grind. Stone mortar and pestles also grind very finely, but unless they're conditioned properly, fine particles of stone can get ground into the spices. Do you want to crush large amounts of spices, seeds, and nuts, or only small amounts? You will find varying sizes from palm size to bowl size, and it may even be handy to have two different sizes if you have the space and budget for it. If you plan to grind a very large amount of spices, getting a spice grinder may be more suitable for your needs. A mortar and pestle is best for just enough spices to create whatever dish or spice mix you immediately want to use.

Pick the right material for your needs. Choose the size you want.

Article: The content of your copy should be inspired and informed by the research you conducted on the product or service. The intended audience will likely have questions that are similar to your research questions. Good copy anticipates these questions—answering them before the customer even has a chance to wonder.  Always write with your audience in mind. Scrutinize each word, phrase, and sentence of the copy to ensure that it will be well received by your target audience. Provide your audience with a comprehensive understanding of the product or service. Explicitly state how the product or service will benefit, improve, or fill the need of your customer or client. Radio ads are frequently tuned out by listeners and extremely short. To compensate for these circumstances, copywriters must capture their audience’s attention quickly and write short, precise, and clear copy that holds their listeners’ attention. Achieving this delicate balance is tricky, but possible.  Do not try to share every detail about the product or service in the copy. Keep your message simple and the focus on the product or service—don’t let the copy get bogged down by an overworked creative format. The product or service should not be overshadowed by a vignette, dialog, or testimonial. Revise your copy with an editing eye. Consider every word, phrase, and sentence carefully. Could you shorten a sentence from 15 words to 6 words? Is that joke relevant? Is there a better word?  Remember that most people who are listening to radio advertisements are driving a car. When the music or show stops, they are apt to change the station. The copy must stop them from changing that station, or get through the other thoughts they have in their head while driving. In addition to presenting the product or service in comprehensive and articulate manner, radio ads must also call its listeners to action. In other words, you must explicitly tell the intended audience what it is you want them to do. Call to actions may include telling your listeners to:  Buy the product or try the service Go to a sale at a specific store Contact the manufacturer or business Attend a concert or club Watch a specific television show Radio ads rely heavily on sound effects and music to help listeners visualize a scene. When incorporated into the copy correctly, sound effects and music can elevate and transform an ad. As you write the words of the radio ad, simultaneously envision the accompanying sound effects and music.  Sound effects and music should never be an afterthought. You may also wish to include unusual voices in your ad.  For instance, if you are selling a beverage, hearing the bottle open can be enticing. If you are selling season tickets to a baseball team, the crack of the bat and roar of the crowd can grab someone's attention. Rely on these other elements to enhance your ad.
Question: What is a summary of what this article is about?
Use your research on the product or service. Create copy that is engaging and simple. Provide your audience with a clear call to action. Use sound effects wisely.
