Question: You look depressed . What's on your mind ?  Well , I had a blood test last week . The doctor said that I have high blood pressure and my blood is thick and sticky . I'm very worried .  Take it easy . When we last talked , you promised there would be more exercises in your life . But now you are putting on some weight .  I have to admit it's easier said than done .  Well , I think it's time for you to change your eating habits and develop a healthy lifestyle . Regular exercise will improve your health .  But you know I'm just not into exercises . And I wouldn't have time for exercises , either .  You can do some jogging . It's easy and it doesn't take much time .  Actually , my doctor said the same thing . 

Answer: No
