yes I had farmers lung when I was 20 , and it knocked me off my feet for months. I went from about 13-14 stone down to less than 8 1/2 ...it was evil ...I now have to avoid any type of dust like the plague. I got FL from grinding barley without a mask , in a confined shed . I was fresh from London and knew nothing , soon found out though ....If you do smell it , make sure you are outside and the wind is blowing any dust/spores away from you , you do not want FL !!! Take care ...
cheers
