  Google analyzes the content, images, and video files in the page, trying to understand what the page is about. This information is stored in the Google index, a huge database that is stored on many, many (many!) computers.   Google Search, or simply Google, is a web search engine developed by Google LLC. It is the most used search engine on the World Wide Web across all platforms, with 92.16% market share as of December 2020, handling more than 5.4 billion searches each day.   Google searches its index of the internet. This might seem trivial but it's an important distinction because it makes the search infinitely faster.  That's exactly what Google does except its index holds pointers to the entire information of the world and is infinitely larger than the index in your average cookbook.   Most search engines build an index based on crawling, which is the process through which engines like Google, Yahoo and others find new pages to index.

A blockage of blood flow to the heart muscle. A heart attack is a medical emergency. A heart attack usually occurs when a blood clot blocks blood flow to the heart. Without blood, tissue loses oxygen and dies. Symptoms include tightness or pain in the chest, neck, back or arms, as well as fatigue, lightheadedness, abnormal heartbeat and anxiety. Women are more likely to have atypical symptoms than men. Treatment ranges from lifestyle changes and cardiac rehabilitation to medication, stents and bypass surgery.     Coronary artery disease (CAD) is the main cause of heart attack. A less common cause is a severe spasm, or sudden contraction, of a coronary artery that can stop blood flow to the heart muscle.   If a piece of plaque cracks, it may cause a blood clot to form and block a coronary artery, cutting off the blood supply to a part of the heart muscle. This causes a heart attack. The heart attack symptoms you feel during a heart attack are caused by your heart musc

Neck pain and tension is often related to your day in and day out posture. For example, slaving over a computer for your job may contribute or even cause a problem known as kyphosis (rounded upper back) as well as a related forward head posture. If so, you likely crane your neck forward so you can see your computer when you work, the road when you drive and more. making the effort to recover—both from the two posture problems mentioned above and any pain or discomfort these may cause—is also good for you in other ways. It can help you become more aware of your body alignment, which in turn may help you prevent future problems. And it can contribute to success at the gym. This is because establishing good form (i.e. body positioning and body alignment) is a known success factor for participation in sports, fitness and dance activities.   Most of the moves will likely help lengthen your neck and balance your head and neck in relation to the rest of your spine—in other wo

  Tumblr is a blogging and social media tool that allows users to publish a "tumblelog", or short blog posts. Tumblr's major differentiator is the free-form nature of the site and the ability of users to heavily customize their own pages.   Tumblr is one of the most popular microblogging sites. Tumblr is a network of millions of user-generated, personal Web sites. It's part blogging platform (like Wordpress, Blogger or Posterous) and part social networking service, letting users create and post their own original content.     Tumblr has an excellent email-or-text-based publishing system that makes it rather easy to post good-looking items to a tumblog with ease.  Tumblr can also absorb audio files, quotes, and pictures that are attached to or in the email or text message. You can even create audio posts (think mini podcast) over a telephone.     According to Quantcast, the primary users of Tumblr in the United States are 18-34 year old females
