conversations.value: First find the number of water breaks James takes: 240 minutes / 20 minutes/water break = 12 water breaks
  Then find the number of sitting breaks James takes: 240 minutes / 120 minutes/sitting break = 2 sitting breaks
  Then subtract the number of sitting breaks from the number of water breaks to find the difference: 12 breaks - 2 breaks = 10 breaks
