People aren't really allergic to dust, but to dust mites. Tiny mites that eat the dust.
Yep, and I am definitely one of 'em - allergic, that is - not a dust mite.
That's.. That's not what dust is...
Yes it is, partially, but people aren't allergic to that part. A lot of people are allergic to the microscopic mites that eat it, though.
Numbers are wrong, otherwise true enough.
