When I'm really peddling I'm concentrating on breathing and pushing, and having to yell out at people would get old and probably affect my pace if I needed to do it for everybody passed.
You have to axe yourself 4 things?
1) Am I on the clock in a race?
2) Will Lance be more disappointed if I lose the race by 3 seconds or if I hurt someone in an accident that could have been avoided.
3) How did that guy just do the "pass and drop"on me while calling out "onyerleft" ?
4) What am I selling?
