Summarize the following:
Keeping your head above water, move sideways by reaching one arm forward and stretching the other out behind you, then bring both arms in towards your body. You can do a kind of sideways breaststroke kick by bending both knees, kicking one out in front of you and the other behind you, then bringing them back together.Reach your arms out at the same time you kick your legs, then bring them all back in at the same time. For this stroke, both your arms and legs will be extending out and away from your body and then circling back in. Do a breaststroke kick while your arms move out straight in front of your chest, then sweep to the side as if you are parting the water in front of you. You should exhale when your hands and knees are coming forward, and come up to inhale when you’re pushing back with your arms and legs. This is similar to the backstroke, but you’ll be floating on your stomach. Do a flutter kick and move your arms forward through the water in a windmill motion. Exhale for 3 arm strokes, then turn your head to the side to inhale on the 4th stroke.

summary: Practice doing a side-stroke. Try a  breaststroke to practice exhaling underwater. Learn the  freestyle once you’re comfortable holding your breath.

If you used natural stone or porcelain tiles for your project, you may not have to buy a special trim. Before you install these tiles along the edge, commission a trained professional to grind your tiles into a bullnose. You can try to do it yourself, but you will need to purchase special equipment and make room for mistakes.  Examples of natural stone include granite, marble, and travertine. A bullnose is where the sharp edge has been ground into a smooth, curved edge. This is another alternative to buying special trims, but you have to do it before you install your tile edges. Keep in mind that this option is not very durable, so it is not recommended for surfaces that will see heavy use, such as stairs. Simply cut sides of the edge tiles with a tile saw. Some tile saws even have a beveled edge, which will make creating the angle even easier. A mitered edge is where the sharp edge has been ground at a 45-degree slant. the edges if you want to keep things simple. This is a third alternative to buying trim tiles. It works best on tiles that have smooth, finished edges, such as mosaic and tumbled stone. Some porcelain tiles may also work. Once you finish grouting the tiles, use a caulking gun or syringe to apply a thin line of caulk to the outside edges of your tiled surface.  Caulk is great for bathrooms, where a water-tight seal is important. This method is not recommended for tiles with raw, coarse, or unfinished edges. This works best on porcelain tiles so that the finishes will match. You will have to commission someone to do this for you, unless you have access to ceramic glaze and a kiln. Painting the tiles with regular acrylic or latex paint is not recommended because it is not durable.

summary: Grind natural stone or porcelain tiles if you don't want to buy trims. Miter the edges of your edge tiles if you don't want to buy trims. Caulk Get raw edges of tiles glazed in a different color to add contrast.

Nearsightedness makes it difficult to see objects far away. This is caused by having an eyeball that is too long, or a cornea that is too curved. This affects the way light is reflected on the retina, which causes blurred vision. Farsightedness makes it difficult to see objects that are up close. This is caused by having an eyeball that is too short, or a cornea that is not curved enough. An Astigmatism is when the eye doesn’t focus light properly into the retina. Astigmatism causes objects to appear blurry and stretched out. It is caused by an irregular shaped cornea. This condition typically comes with age (over 40). This condition makes it difficult for the eye to focus on objects clearly. Presbyopia is caused by a loss of flexibility and thickening of the lens inside the eye.
summary: Identify nearsightedness. Identify farsightedness. Identify astigmatism. Identify presbyopia.
