What's the matter with me , Doctor ? I feel so tired these days .   Is your blood pressure , I'm afraid . It's far too high .   And what's the cause of that ?   Overwork-amongst other things . You can't work 24 hours a day . You ' Ve got to slow down .   But I can't just slow down .   You've got to , I'm afraid . And look at this . You weigh 200 stones . That's too much for a man of your size .   You mean I've got to lose weight ?   Yes . You've got to cut down on bread and potatoes and take more exercise .
