Yes
 I read somewhere that twins because of the egg splitting into
 feel half of them is gone when one dies
 i heard Elvis talk to the wall of his own reflection as if he was
 talking to his late brother Jessie that died at birth
 that they can be a thousands mile away, but as long as they
 are still alive still feel whole (like one person) but when one
 pass away they one can feel as if he or she is only one half
  
 twins would explain that better than we can, but i think i can
 understand
  
 still they look around age 40 instead of mid 60's when Jim died
 last year and Jon this month
  
 will miss both of them, funny and was country music only
 twins to hit the music chart
