conversations.value: James decides to bulk up.  He weighs 120 kg and gains 20% of his body weight in muscle and 1 quarter that much in fat.  How much does he weigh now?
conversations.from: assistant
conversations.value: He gains 120*.2=24 kg in muscles
  So he gains 24/4=6 kg of fat
  That means he gains a total of 24+6=30 kg of bodyweight
  So his new body weight is 120+30=150 kg
