disconcerting

Why does all of my sleep-clothes smell musky? It is so difficult to tell whether a stained, pilled old t-shirt is clean or not without the advantage of smell. I should really just toss them all into the washing machine so that I don't get scabies from wearing dirty laundry. I did get scabies once in grade 5 though (not from dirty laundry, I hope). It was the second most embarrassing diagnosis I've received from a doctor.
