   MTBF is a measure for the rate of failures *during normal lifetime* - ie.   
      
   1 / failure rate   
      
   It is *not* the lifetime of a component. MTBF is a measure for failures   
   during the flat part of the bathtub curve. Failures due to end of lifetime   
   (like normal, not-premature wearout on a fan) are not part of MTBF.
