historical-nonfiction:

Chemist Carl Wilhelm Scheele discovered or identified oxygen, molybdenum, tungsten, barium, hydrogen and chlorine.  He greatly advanced science. However, he died young and his discoveries were cut short. Why?

Chemist Carl Wilhelm Scheele died young, because he was so eager to learn about the chemicals he studied, that he tasted and smelled them all the time.

Of course, we now know that tasting and smelling chemicals is bad for you. Poor Scheele did not – and died because of it.
