discover this?

S2: I often had chest pains, but at the beginning I paid no attention until one day I went to the doctor. I was examined carefully and I was diagnosed as having a cancer. On learning this, I was very astonished at first, and then I felt very depressed. I put my head on the doctor's desk in despair.

S1: What did you do with it?

S2: I told myself to get started and never to lose heart. In the next few months, I had to have two operations and to undergo chemotherapy treatment.

S1: How did you feel at that time? Was it very painful?

S2: Of course it was very painful and it was hard for you to imagine that pain. I lost weight and felt so tired that I had to sleep over twelve hours per day.

S1: But you lived through the period and succeeded in not letting it beat you.

S2: Yes, I did. Next, I needed to ride my bike 30-50 miles a day and I believed I could realize my dream by working hard and I have.

S1: Oh, you're really a great man. Congratulations again!

S2: Thank you.
