Exhaustion: Mental vs. Physical

I’m a student. I’m a nurse. I’m a crossfitter. I haven’t quite figured out what is the most exhausting.

I spent the entire weekend studying for finals. Today I hit ‘the wall’.

That ‘wall’ is different for each, but I gotta tell ya.. that mental ‘wall’ can deliver a stronger blow than any crossfit WOD or 16 hour shift.
