conversations.value: He brushes his teeth 3 times a day, after breakfast, lunch and dinner. He brushes for 2 minutes so that’s 3*2 = 6 minutes per day.
  He brushes 6 minutes per day so after 30 days he has brushed 6*30 = 180 minutes
  There are 60 minutes in 1 hour and he brushes for 180 minutes so that’s 180/60 = 3 hours
