Water warts appear as pink colored, dome-shaped lumps, which can appear anywhere on the body. The warts tend to grow in clusters, leading to pear or dome shaped clumps. The most characteristic feature of water warts is that they have a visible hole or point right in the center. The medical term for this is "central umbilication". Water warts should not feel painful, but the virus may trigger an immune response, causing the wart and the surrounding skin to feel itchy. The water wart virus is contagious, meaning it can easily be transmitted from one person to another. The water wart virus can be transmitted through fomites (inanimate objects capable of carrying infectious organisms) such as towels, bedsheets, doorknobs, clothing, etc. The virus may also be transmitted through sexual contact. The water wart virus can also spread from one part of your body through the other, via auto-inocculation. This happens when you scratch or touch an existing wart, and then touch other parts of your body, causing multiple lesions. This common viral disease has a higher incidence in: Children: Children are particularly susceptible to auto-inoculation, and may have widespread clusters of lesions. The water wart virus spreads most easily through direct skin-to-skin contact, but kids can get it by touching objects that have the virus on them, such as toys, clothing, towels, and bedding. It can also spread in water, so kids often get water warts from swimming in a public pool. Sexually active adults. Water wart infections are often transmitted through sexual intercourse and affect the genitals, buttocks, lower abdomen and inner thighs. In rare cases, infections are also found on the lips, mouth and eyelids. People with immune deficiencies: People whose immune systems have been weakened by HIV, cancer treatment, or long-term steroid use are more vulnerable to infection by the water wart virus. Since water warts are contagious and can spread to other body parts, an infected person should follow a number of precautions to prevent the water warts from spreading or being transmitted to another person: Try to cover each growth with clothing or a watertight bandage, especially before participating in activities in which equipment is shared or skin contact can occur, like swimming and wrestling. Keep the areas with growths clean and change each bandage daily or when it becomes dirty. Do not scratch or rub water wart growths, and regularly wash your hands with antibacterial soap. Do not shave over areas that have bumps, as the razor could easily spread the virus from one part of the body to the other.

Summary: Recognize what water warts look and feel like. Understand how water warts are transmitted. Be aware if you are at risk of developing water warts. Take steps to prevent the spread of water warts.

Parallax refers to the apparent difference in position of an observed object depending on your vantage point. The right parallax correction depends on which celestial body you're observing (i.e., the sun, the moon, or a planet) and the altitude you observed. Check the parallax correction tables on page A2 of your Nautical Almanac. Add the parallax correction after adjusting for index error, dip, refraction, and semi-diameter to get the true altitude of your observed object. The parallax correction accounts for the difference between your vantage point on the surface of the Earth and what you would see from the center of the Earth. The combined correction for parallax, semi-diameter, and refraction is known as the "third correction." For example, if your observed altitude for the sun was 38 10.60' and you made your observation in April, you might make your corrections as follows: 38 10.60' + 1.2' (index error) = 38 11.8' 38 11.8' - 9.16' (dip) = 38 2.64' 38 2.64' - 1.1' (refraction) = 38 1.54' 38 1.54' + 15.9' (semi-diameter) = 38 17.44' 38 17.44' + 0.1' (parallax) = 38 17.45' (true altitude)

Summary: Make a parallax correction using your Nautical Almanac.

Try to make small, measurable gains with each workout. When you work out your shoulders, lift heavy, and stick to 4-7 reps per set. Increase either the weight or the rep number very slightly with each workout. This way, you'll set a pattern of incremental, sustainable gain. Keep a practice of "progressive overload." Lift more and more weight over time so that you are always pushing the limits of your muscles. You will not get bigger shoulder muscles without getting stronger. Imagine that in your most recent workout, you lifted a 55 lb. dumbbell shoulder press in sets of seven reps. Next time, push yourself to do eight reps with the same weight. Alternately, move up to 60 lbs and do seven reps again. The deltoid (shoulder) muscle comprises three sections: the anterior (front) head, the lateral (middle/medial) head, and the posterior (rear) head. Try to build muscle in each of these areas in order to balance out your shoulders. The wider and thicker your shoulders are, the more impressive they will appear.
Summary: Lift heavy weights, and focus on steady gains. Develop all three heads of the deltoid muscle.
