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.
And of course, dried blood again can cause black specks in mucus, but in a different way than via nose canals. In certain rare infections (fungal in nature) such as mucormycosis and aspergillosis, blood can be found in the lungs that can be expelled with mucus.
