You know you're an addicted road cyclist when . . . . . . your surgeon says you need a heart valve replacement and you insist on presta. . . . you find nothing disgusting about discussing the connection between hydration and urine color. . . . you empathize with roadkill. . . . you take your bike when shopping for a motor vehicle, just to make sure it'll fit inside. . . . good cycling roads are the main thing that matters when hunting for a new house. . . . you view crashes as an opportunity to upgrade components. . . . you say "On your left!" when walking around another pedestrian. . . . dessert is the first thing you order when eating out. . . . you smile at someone, who informs you that you have bugs in your teeth.
