Sherlock Holmes may not have played games, but you can. Certain games can help to boost your powers of observation as well as your memory, so find some that suit you, test yourself, and keep your brain well-trained. Try a "spot the difference game." In these you will be shown two or three pictures that appear identical, and asked to find small differences. You will have to look at the images very carefully. Memory cards are a good way to retain detail. You will have a set of cards face down in front of you and each turn will turn two over, trying to find matches. You must remember what is on each card and where it sits in order to do well. Does your mind wander much? Don't worry, almost half of working adults are not always focused on the task at hand. But a good detective is able to focus all of her mental powers on the problem at hand. She is unblinking and able to stay on task. To have a good eye for detail, you'll need to increase your concentration. Cut out distractions. One thing that might be hindering you is distraction. Cut out things that divert your attention. Power down your phone, shut off your computer. Practice self-discipline. When you find your mind wandering, consciously force yourself back to the problem. Tell it to "stop." Avoid multitasking. Multitasking may seem like a smart way to work and to get more done. However, studies show that multi-taskers take longer to complete tasks and make more mistakes. You can't afford small errors as a detective. Avoid! Practice meditation. According to one study, people who meditate appear to have lower activity in a part of the brain called the "posterior cingulate cortex (PCC)," which is controls the wandering mind. Better control over the PCC may mean that it will be easier for you to stay on task. Scientists in the field or lab have to train their attention, and one way they do this is by taking field notes. Writing down information in note form forces you to separate what is relevant and important from what is not; with practice it should help you develop a quicker eye for detail. You will often find that, on turning the notes over in your mind, unseen connections will emerge. Keep some notes in a journal or simple notebook. It probably helps to carry this with you at all times, in case you need to jot something down on the spot. These are sometimes called "jottings." Later, when you have time, you can revisit your jottings and put them into a more coherent narrative. Reviewing, reworking, and rewriting your jottings into detailed notes will strengthen your grasp of the information. When you first encounter information, your brain puts it in "temporary storage." For maximum recall, however, you want to encourage the brain to transfer data into your long-term memory, minimizing the loss of any detail or information. That way, you will be able remember it and apply it to your case quickly and efficiently. Try to create links between new information and what you already know. Use familiar examples or analogies; create acronyms, rhymes, word play, or jingles. Make mental associations to images. Some people find the so-called "memory palace" or method of loci technique useful. This is when you visualize a detailed mental "storage" facility, sometimes a house with different rooms, and walk yourself through the facility in order to retrieve information. Sherlock himself sometimes uses this method. Be as active as possible in learning. Ask yourself questions about information and try to answer them. Take time regularly to review information, including your field notes.

summary: Play games. Concentrate. Take detailed field notes. Improve your memory recall.

Choose a major that will allow you to become a teacher -- it may be education, but some states don't require it. Most schools have a grade point minimum for students -- if your grades are too low you will not be able to continue in the education program. If you are worried about your grades, meet with the professors to ask for help in raising your scores. Every student in college has an advisor, and he or she is there to help you get through and be successful. Advisors help you choose your courses and make sure that you're on track to graduate. If you are having trouble in a class, an advisor can also help you figure out ways to improve. Don't let the work get away from you, especially the courses you find difficult. Stay current with your assignments and readings. These classes are to help you achieve your goal to be a health teacher, and all of them are important. Even if they are general education courses, all of them contribute to the GPA that can keep you from achieving your goal. If you are not as strong in some of your classes, find help through the tutoring center on campus or through your professor. Even if you aren't having difficulties in your classes, get to know the faculty. These will be the people writing you letters of recommendation and helping you find a job after you graduate. You also might find a professor that can be a mentor to you and help you long after you have left school. A mentor would be there to help in your early years of teaching when you have questions or concerns. All schools have different clubs and groups, and they are a great way to meet like-minded students. Some groups might be involved in health outreach into the community or volunteering in the schools. Look for the ones that most appeal to you. These groups and opportunities can help you further refine your career interests and goals. Most education degrees require students to work with a veteran teacher in the schools. You might be asked to prepare and teach different units or assist the main teacher in grading. These assignments typically last a semester or a year, and are usually at different levels within your chosen focus area. It's a great way to get hands-on experience and start to narrow down exactly where and what you want to teach.

summary: Be aware of the requirements for becoming a health teacher as determined by your university. Meet frequently with your advisor. Be engaged in your courses. Meet with your professors. Look for extracurricular and volunteer opportunities that relate to your studies. Complete your student teaching component.

This is considered the best way to diagnose an enlarged heart. An echo is a painless procedure in which the doctor uses ultrasound technology to examine the movement of blood through your heart on a monitor. The anatomical structure and functional activities of the four chambers of your heart can be assessed with this test. The valves of your heart can also be observed If your doctor finds that the walls of your heart's left ventricle are larger than 1.5 centimeters (about half an inch), your heart is considered enlarged. This test records the electrical activities of your heart and can detect irregularities in your heart's rhythm. It can also aid in analyzing how a particular chamber of the heart has been enlarged. The heart's activities are recorded on a graph. An EKG provides information about heart rate, rhythm, and any conduction defects in the heart. If you and your doctor suspect you have an enlarged heart, your doctor will probably make you get an X-ray. X-ray images can help your doctor see the size and condition of your heart. An X-ray can also help to determine if you have any irregular enlargement of parts of your heart, or if the shape of your heart has changed. An enlarged heart may disrupt the production and levels of certain substances in your blood. By measuring the amount of these substances in your blood, a doctor can determine if you have an enlarged heart or a related condition. Catheterization involves inserting a tube (catheter) into your groin and threading it through your body into your heart. A small sample of heart tissue can be removed and examined later. This technique is not usually necessary, since other techniques of diagnosis are less invasive and easier to perform. During the procedure, the doctor might be able to capture images of the heart to visualize what your heart looks like.
summary: Have an echocardiogram (echo) done. Ask your doctor to take an X-ray. Get blood tests. Talk to your doctor about a cardiac catheterization and biopsy.
