Well, good morning, Tom. I haven't seen you for a long time. What seems to be the trouble now?
I feel very tired. I've got a bad headache, and I can't sleep well almost every night.
Have you been eating properly? Eating the right kind of food is very important for your health, you know?
Well, I haven't been eating too well, I guess. I have a lot of work to do, and I usually only have enough time to have a sandwich, and a cup of coffee for lunch.
And what about dinner?
Sometimes I'm too tired to eat anything at all.
It's too bad, you must have a well balanced diet. But I think the most important thing for you to do right now, is to have a good rest.
Yes, I agree.
