Writing appears more forgiving because there is no compiler or interpreter catching your its/it’s issues or reminding you of the rules regarding that or which. Here’s the rub: there is a compiler and it’s fucking brutal. It’s your readers.
The fact that smoke calms bees has been known since ancient times; however, the scientific explanation was unknown until the 20th century and is still not fully understood. Smoke masks alarm pheromones (which include various chemicals, e.g., isopentyl acetate) that are released by guard bees or bees that are injured during a beekeeper's inspection. The smoke creates an opportunity for the beekeeper to open the beehive and work while the colony's defensive response is interrupted. In addition, smoke initiates a feeding response in anticipation of possible hive abandonment due to fire. When a bee consumes honey the bee's abdomen distends, making it difficult to make the necessary flexes to sting. (The latter has always been the primary explanation of the smoker's effect, since this behavior of bees is easily observable.)
