Input:  Person1:     Why are there still so many people overweight despite the current fitness craze ?  
 Person2:  Well , there are certain factors that effect people's size and weight .  
 Person1:      What are they ?  
 Person2:  One study said that low-income groups have a higher percentage of over-weight people than higher income families .  
 Person1:      Why ?  
 Person2:  The survey said that the low , income groups eat more junk food on a daily basis .  
 Person1:      That makes sense . Probably less time to make dinner and the junk food is cheaper .  
 Person2:  And junk food contains lots of fat and oil . There is one final reason why so many people are fat .  
 Person1:      What's that ?  
 Person2:  Nobody exercises any more-not even kids ! The average American home has the TV on for 6 hours a day !  
 Person1:      Wow ! No wonder people are so fat . Say , Carl , looks like you could be doing a bit more exercising .  
 Person2:  Yeah , I guess so .  
 Person1:      You should consider eating healthier food and getting some more exercise .  
 Person2:  Hey , I started a diet and lost 10 pounds .  
 Person1:      So what happened ?  
 Person2:  Well , I quit and gained it back plus 5 pounds .  
 Person1:      You should have kept trying .
