Vending machines can serve a multitude of purposes for consumers that range from providing food items to exchanging coins for paper money (or vice versa). Because the pathway to starting a vending machine business is so accessible, the sum of costs involved in operating the machine(s) is sometimes overlooked.
Cancer can also cause blood thickening. Not all blood clots are caused by thick blood. Blood clots leading to heart attacks and strokes can be formed when thin blood comes into contact with plaque, which triggers a blood clot. Some blood clots result from sluggish blood flow or poor circulation.
The current mythology is that arterial blood and that exposed to the air (bleeding) is red because oxygen binds with the hemoglobin resulting is a red color. Venous blood is bluish because it is oxygen depleted which results in a blue color. The veins that carry the venous blood are just under the skin hence this is the blue blood you see. The arterial blood is carried in the arteries which are deep in the body and not seen through the skin.
