Working on a story during my latest blood donation. (My 67th!)

*The quote at the top has primarily been credited to sportswriter Red Smith.  But an interesting article at Quote Investigator gives a number of variants, some predating Smith's 1949 version.  I think I prefer Paul Gallico's 1946 version best: "It is only when you open your veins and bleed onto the page a little that you establish contact with your reader."
