F: Would you please tell me something about your best holiday, Jason? ,M: Well, it was my trip to Nepal. We went there 10 years ago, walking in the mountains for 20 days. ,F: That's a long time. How far did you walk everyday? ,M: 15 kilometers or so. We had to climb up and down a lot everyday. At times, it was hard to walk as the air there was very thin and we had a lots of problems breathing, which made me anxious and depressed. ,F: What kind of equipment did you take? ,M: Only a bag, a sleeping bag and some warm clothes. ,F: And how was the food? ,M: There was rice and vegetables. Normally no meat, but it was OK. ,F: What was the best thing about the trip? ,M: The walking and the exercise. I hate sitting in the sun and like walking in the countryside. The air was very clean and it was very quiet. Nepal is a good place. You must go.
