Have you ever wondered how much of Omega-3's you need to take and what brand should you get? For maximum absorption and potency, studies have shown that Omega-3 supplements should be in the same natural triglyceride form as in the fish. The types of Omega-3 fatty acids most important to eye and heart health are EPA and DHA. The recommended daily dose of total EPA and DHA is 2 grams for healthy adults. For patients with dry eyes or age-related macular degeneration, the recommended daily dose is 4 grams. For children, the recommended daily dose is half a gram a day. When selecting a brand of Omega's, always check the amount of Omega-6 fatty acids. Western diets are already rich in Omega-6's. Too much of Omega-6's compared to Omega-3's can increase inflammation in the body. Given the quantity of Omega-6's in our diets, taking a supplement with omega6 fatty acids is unnecessary in most cases and possibly deleterious in some. In addition to the amount and type of Omega's in the supplements, consider the purification method. Raw fish oil must be purified with ethyl alcohol to remove contaminants, particularly mercury. High quality fish oil products remove the ethyl alcohol through a process called trans-esterification, which transforms fish oils back to the natural triglyceride form. Many manufacturers, however, choose to leave the ethyl alcohol in the preparation. Fish oils containing ethyl alcohol usually have only small amounts of EPA and DHA. One would have to take many more of them a day in order to get the recommended daily amount of EPA and DHA.

In the original Star Wars movie, there is a scene where Luke Skywalker is watching a sunset on his home planet of Tatooine. The Sci-Fi aspect of this is there are two setting suns. Nowadays, the effect would be created by a computer, but back then, George Lucas only had to use an optical illusion. The scene was filmed in Tunisia where the setting twin suns are a natural phenomenon. The heat of the desert creates a temperature gradient in the atmosphere where cooler air is denser than hotter air. This produces different indices of refraction that bend light and shift the apparent position of an image in the distance. So you're just seeing two copies of the same sun with no special effects added.
