To me the blues is an infection. I don't think it's necessarily a melancholy thing the blues can be really positive and I think I think anyone and everyone can have a place for the blues. It need not always a woeful sorrowful thing. It's more reflective it reminds you to feel.
One could not have isolated this retrovirus without knowledge of other retroviruses that's obvious. But I believe we have answered the criteria of isolation.
