    	Whoops!  Didn't mean to sound imperious  :-)  Besides, I'll bet you 
    _sit_ corrected, not many of us stand while typing.
    
    	Anyway, the only difference that's easy to see/feel is if you smack 
    the rollbar stuff (hard, between two unforgiving objects), you can feel 
    the dent afterwards, even if you can't see it.  Pipe insulation returns 
    completely.  This is an indication of how much energy it has absorbed.  
    All the best armor plating and bullet proofing is one-use, sacrificial 
    stuff.
