Backpain and happines

How come some people find happines in whats going on around them, while having major backpain through the spine?

While working at the hospital, I've encountered dosen of pasients with BIG PAIN. And me, while being at a third party, without any diagonistic knowlege of my pasient, I've observed different reactions.

I kinda feel like pain and happines is one of the most valuable things on earth (in the way that you feel alive), yet being none of my business witch then making me careless.

While working at the hospital, with my professional carefull person, saying things and asking about the pasients feelings and need, I myself find it uninteresting on the private base.

Dont take me wrong, I love my job and I teach alot about humans reactions and feelings. But these people aren't those I care about.
