IANAD, but your example of the appendix is not a clear cut case. How most of the human body actually functions on a microbial level is not understood. The appendix could serve a function that is perhaps redundant, but helpful.

At the bare minimum, you need to move closer to where you work. Your commute is costing you your health and is eating your paycheck. Looking at the money you are making versus the costs, you might be better off working at the 7-11 down the street.
Where does your social life fit in to this? I know when I work a 60+ hour week I need the weekend just to unwind, let alone see friends or do things I enjoy.
My solution, get an apartment within 5 miles of your work and then ride a bicycle there.
