If I'm flogging myself on some random mountain at the Volta a Portugal in 38 degree weather, dropped a long time ago by the leading group, and well ahead of the gruppetto, in no man's land, on a small random Portuguese continental team making €900 a month (what Paco Mancebo was earning), then I would have plenty of time to do some deep soul searching, then I would work that a) It's not going to happen, time to step back and find a real job, or b) if all I have to do is extract some blood and re-inject it back in at a later date, and get some results, and therefore get noticed by a bigger team and earn more money, then I would probably lean towards option b.
Whether you dope or not isn't going to change anything, and if that is the system, are you doing a disservice by not taking option b?
