conversations.value: 5 nights a week she sleeps for 6 hours so she sleeps 5*6 = 30 hours
  2 nights a week she sleeps for 9 hours so she sleeps 2*9 = 18 hours
  2 days a week she naps for 1 hour so she sleeps 2*1 = 2 hours
  Over 1 week she sleeps 30+18+2 = 50 hours
  Over 4 weeks she sleeps 4*50 = 200 hours
