An example of an idiom in science writing:
"Circulating RBCs accumulate various traumatic lesions over time. They are thought to endure a kind of 'death by a thousand cuts'. Lacking a nucleus and translational machinery, RBCs start their 4-month journey through the circulation with all of the enzymes that they will ever have, and these stores gradually become depleted. RBCs may suffer mechanical damage due to shear forces in the circulation. Perhaps most importantly, RBCs constantly encounter reactive oxygen species, both in the circulation and generated internally, as approximately 3% of haemoglobin undergoes auto-oxidation daily."
