Heres one way to put it.

If your friend or a member of your family dies, its sad but it passes on. It you get your leg cut off accidentally by snapped razor wire or something you will never walk again! But then again, the pysical pain will wear off (if he/she survives for long enough) and you're left with the emotional pain of never walking again. So its a difficult one to answer. I don't have an answer actually. Well, whatever.
