Like Asian earwax is super dry and flaky, while European earwax looks like yellow green toxic goop.
So you have different genes and on top of that different diets (I had Indian neighbors once, you could smell the curry in the entire hallway of the building 24/7. But they obviously use a ton of spices when cooking).
As a central European Caucasian guy I personally start to smell really bad without deodorant just after a day or so. No matter how often I shower or what I eat. I also tried to switch to deodorant without aluminum and that didn’t work out at all :-/
