This is very powerful and really great ideas where to reflect on and see what an individual is willing to let go of. 
I have set myself my own challenge by changing my diet from vegan to raw vegan... just to challenge myself and see how my physical and spiritual body reacted. I have been eating raw consistently for almost 6 months now. And I will keep it that way. I am pretty sure I will soon switch to a more monogenic diet... like only one type of fruit per meal. 
And yes, there are so many things we depend on...I mean just the electricity is a big dependency, or food, if not having our own garden and water, if not having our own well!!!
