Sure. Training for a marathon puts you at risk of injury. That doesn't mean that everyone who runs a marathon has an injury, or that everyone with ambitious running goals should go relax on the beach instead. Ultimately, there is no objective standpoint from which to say that people should choose different goals, because goals are based on personal subjective values.

Perfect example of the appeal to tradition fallacy.
