Apparently, people from different ethnic groups have different kinds of earwax:
[Researchers] studied genes of people from 33 populations and found dry earwax in up to 95 percent of East Asians, but in no more than 3 percent of people of European and African origin, who tend to have wetter earwax.
Who’d a thunk it, eh?
