  @sumseno,
  This is not an absolute number, but I guess its easier to quote a single number for the purpose of teaching. Its is the average no. of beats for an adult.
  The number of beats per minute varries with age, sex and how fit an individual is. For instance, athletes will have less beats per minutes because exercises increase the size of the heart making it more efficient at pumping blood.
