It's... not an option. I live in a slum in Vietnam. This is actually quite nice in many ways, it is overall quiet and safe! However, flooding, weird plumbing, humidity, and general low-level chaos make it impossible to keep particularly clean.
It would be like being afraid of air.
Like, I used to be afraid of spiders. Then I immigrated here and spiders were just common enough that after a period of discomfort I just had to give up and accept them.
