Note: blood thinners are medications that people use to prevent their blood from coagulating and forming clots. These clots can cause heart attacks, especially if an artery is already blocked by fatty deposits due atherosclerosis. Note: it can also be used in other sticky situations (pun intended!) as well. If you get sap or glue on your hands, try rubbing them with butter before washing them with soap and water. Photos: 24. With Associates via flickr, 23. Hans Hillewaert via wikimedia commons, 21.
