Happy Belmont Day!

Also, David Sessions tells us whether racehorses do, indeed, pee like racehorses:

The popular notion of incontinent racehorses seems to have roots in the late 1970s, when trainers began the widespread use of diuretics like Lasix (furosemide). Lasix inhibits the absorption of sodium and draws water into the bladder. This causes the horse to excrete more fluids, which could, in theory, make a horse lighter on its feet and faster on the track. Depending on the dose, a Lasix treatment could cause a horse to move several gallons of urine within an hour, which could translate to a quick drop of 10 pounds from a horse’s body weight before a race.
