article: This is one of the easiest places to measure your heartbeat because you have a large artery right below the skin. Each time your heartbeats, you will feel a pulse as the blood rushes through your artery. Hold out one arm, palm up. Gently press your index finger and middle fingers to the inside of your wrist between the bone and tendon near your radial artery. This will be approximately one inch below your wrist on the same side as your thumb. You should feel soft tissue beneath your fingers, not bone. You may need to move your fingers around or press slightly harder until you feel it. Count the number of beats for 15 seconds and multiply by 4 to get the number of beats per minute. Use a clock to measure the 15 seconds rather than trying to simultaneously count your pulse and the seconds. This is another location where you should be able to easily and quickly find a strong pulse. Put your index and middle finger to the left of your windpipe where your neck connects to the tissues underneath your jaw. You should be able to feel your pulse on either side of your windpipe, but it might be easier to find on the left side. You may need to move your fingers around and press a little harder until you feel it. Use a clock or stopwatch to keep track of 15 seconds, count the pulses you feel, and then multiply by four. You should get about the same result when you measure your pulse at your wrist or your neck. Your resting heart rate is the number of beats per minute when you are inactive for at least five minutes; however, if you were exercising, it may take longer for your heart rate to slow down. A person's resting heart rate naturally varies based on how active you are, how fit you are, how warm or cold it is, whether you are standing, sitting, or lying down, your emotional state, your body size and what medications you are on. Consult a doctor if: Your resting heart rate is usually over 100 beats per minute. This is called tachycardia. Your resting heart rate is below 60 beats per minute, if you are not an athlete. This is bradycardia. Other symptoms that may accompany this condition include fainting, dizziness, or being out of breath. If you are an athlete, a low heartbeat may mean you are in good shape. However, it should not be below 40. Your heartbeat is irregular.

article: Around a quarter of the human body cells are red blood cells, or erythrocytes. These RBCs are developed in the bone marrow produced at approximately 2.4 million red blood cells per second. Erythrocytes circulate in the body for 100 to 120 days. It is the same reason why we can only donate blood once every 3 to 4 months. Men have an average of 5.2 million RBCs per cubic millimeter meanwhile 4.6 million in women. If you are a regular blood donor, you'll notice that there are more men who passed the blood donation screening than women. The iron-rich protein known as hemoglobin is the main component of the red blood cells. It is responsible for the red color as iron binds with oxygen. Each hemoglobin molecule has four iron atoms and each of which binds to 1 oxygen molecule with 2 oxygen atoms. Around 33% of an erythrocyte is hemoglobin normally 15.5 g/dL in men and 14 g/dL in women. Red blood cells play an important role in transporting oxygen-rich blood from the lungs to the tissues and cells. RBCs have cell membranes composed of lipids and proteins essential for physiological function while working within the capillary network through the circulatory system. In addition, red blood cells aid in the removal of carbon dioxide. They contain the carbonic anhydrase enzyme which allows for a reaction of water and carbon dioxide to form carbonic acid and separate hydrogen and bicarbonate ions. Hydrogen ions bind with hemoglobin while bicarbonate ions go to the plasma removing approximately 70% of carbon dioxide. Twenty percent of carbon dioxide binds with hemoglobin which then released in the lungs. Meanwhile, the remaining 7% gets dissolved in the plasma.

Allow your tools to soak for 1 to 3 days. Scrub the tools with a scouring pad. Rinse out the container and fill it with clean water. Add baking soda to the water. Place the tools in the water. Scrub the tools with steel wool. Wipe the tools with denatured alcohol."

If the tool is part of a larger machine, such as a table saw, disassemble your unit. Wash all of the tools or parts to be treated for rust in a mixture of grease-cutting dish detergent and warm water to remove the oils and dirt. You can use a plastic container, pot, or tub, as long as it's large enough to submerge the tools. Choose a container that you can set aside for one to three days. White vinegar is acidic, so it will cut through the rust, making it easier to remove. While the amount of white vinegar will vary depending on how many tools you are cleaning and how big they are, track how much you add to the container so that you can properly measure your salt. You should add roughly cup (60 milliliters) of salt for each quart (1 liter) of vinegar. The salt will increase the acidity of the vinegar so that the solution dissolves the rust quicker. Spread the salt evenly over the vinegar soak. The vinegar and salt need time to break down the rust so that it can be scrubbed from the tools. The longer you allow your tools to remain in the vinegar, the easier it will be to remove the rust. Place the container in a secure location so that children and animals won't get into it. For example, you could lock it in your garage or shed. Pull out any tools with hinges or moving parts occasionally to move them around. This helps work out the rust from the crevices. After you remove the tools from the vinegar solution, vigorously rub your tools to buff away the rust. Continue to scrub the tools until they are completely free of rust. If the rust is thick, use a metal bristle brush. Use a small, firm toothbrush in circular motions for hard to reach areas. Pour out the vinegar solution and wash out the tub. Fill the tub with enough clean water to match the amount of vinegar solution that you'd used. The baking soda will neutralize the acid from the vinegar so that it doesn't remain on your tools. Use about cup (60 milliliters) of baking soda for each quart (1 liter) of water. Mix the baking soda into the water to create a solution. Make sure that your tools are submerged in the baking soda solution. Allow the tools to soak for ten minutes before removing them. Dry them well with a clean towel. Use 0000 steel wool to buff the tools and remove any remaining spots. Your tools should be free of rust. Apply denatured alcohol to a clean cloth and rub it onto the tools. The alcohol will help you make sure that no water remains on your tools. Water could cause more rust. Polish the tool with camellia oil to prevent more rust.
