Now , what seems to be the trouble ?   It's nothing serious . But I always have a headache , and I haven't slept properly for several weeks . I've also lost appetite and my eyes are burning .   Mm , you do look rather pale . Let me take your temperature . Would you put the thermometer under your arm , please ? Now , let me listen to your pulse . Mm , do you feel weak ?   Yes , I never seem to have any energy .   I'll give you a blood test . Would you roll up your sleeve ? Just as I thought . You're anemic . You'd better pay more attention to your diet . Eat plenty of fresh fruit and vegetables and food high in protein . And don't stay up late working . Try to get more rest .   Thank you .
