Unless you get struck my lightning or get squished by a big rock or a large mammal eats you or you **** your pants.
This kind of attitude is fine to have as a personal philosophy but it's a little disrespectful to people who enjoy the trails in a different way by more or less saying their accomplishment as they see it is invalid. If someone wants to risk failure by defining success in a specific manner you should be open to acknowledging their potential for failure because to not do it is to disregard their personal success.
