So, she's a crusader. Finding things and people that don't fit her (or the laws' she lives with) ideas of what's Right, and doing what she can to fix them, by bringing them to public and legal scrutiny. While one can see where those with guilty consciences might prefer she were less intensely thorough about her actions, and some of us would like to see her bring a healthier approach by way of taking better care of herself and focusing more on leading by positive example than so actively resisting these perceived-as-negative examples, in the end, it is her choice whether to crusade, her choice of how to crusade, and her choice which crusades she takes on.
As one who has taken on a health crusade as my life's purpose and legacy to my fallen angel, I can definitely relate to Having A Purpose and working on Making Things Better. While monetary gains are nice in a life where money is better to have than not, such concerns are secondary to the ideas of seeing that those who are violating the laws and/or treating people badly be brought to justice (in Barb's case), and that those committed to improving their health and wealth have access to the best, simplest easiest body-fuel available (in my case)
For my part, I will suggest Barb take better care of herself so that she may continue to fight more of the good fights, and fight them better - otherwise, a simple "Excelsior!" for her courage, and gratitude that there are more who choose to live life fully standing up for their principles, rather than merely existing, drifting from one expediency to the next and sniping from the sidelines as anonymous cowards...
