One of the dangers of the clotting cascade is that it could conceivably trigger the formation of a clot that would not stop forming/growing until all the blood in the body had clotted (or clots would move to areas of the body that would quickly cause the death of the organism). What prevents this?
Aspirin. It’s critical that everyone take at least a low dose of aspirin at least once a year.

fibrin
plasmin
