"Cystralline silica is found in materials such as concrete, masonry, and rock. When these materials are made into a fine dust and suspended in the air, breathing in these fine particles can produce lung damage. Silicosis can be totally disabling and may lead to death." (Source: https://www.cdc.gov/niosh/docs/97-101/pdfs/97-101.pdf?id=10.26616/NIOSHPUB97101#). So, now, there is cement in your lungs, damaging it, and you have to live with that for the rest of your life now.
