Question: M: This saying has been scientifically proven! A year-long study of heart attack victims done at the Oakhurst Health Research Institute in California found that of those patients who spent half an hour a day watching comedy videos, 10 percent had a second heart attack, whereas 30 percent of those who did not watch had a second attack. W: Wow! Laughter is really a good medicine to patients. Can you give us another example? M: Sure! Norman Cousins, editor of the Saturday Review, learned this during a battle with an illness. He discovered that his condition improved when he enjoyed himself and watched funny movies. W: You said Norman learned this? Do we have to learn to laugh? M: Not necessarily. Since laughing is something people can do sitting down, costs no money, and requires no special exercise equipment or skill, it's the perfect workout for anyone who doesn't have the time or desire to participate in a regular fitness program. W: Oh. Do you have such a program to offer to the general public? M: Yes, we do. It's called the Smile Time-Out. You take a deep breath, smile, exhale, and say "Aaah" while visualizing all your muscles and cells smiling. Then add to that a memory of a time you felt really good and laughed and laughed. W: What about the situation in which you aren't in a mood to laugh? M: Even when you fake a smile or laugh, you get the same physiological benefits as when it's the real thing, because your mind is smart, but your body is stupid and can't tell the difference!

Question: W: Hi. M: You look great! Have you been on vacation? W: Yeah, I have. I was on the West Coast. M: Nice! How was it? W: Great. I had a wonderful time. It was really nice to get away from work. M: Where did you go? W: Los Angeles and San Francisco. M: How did you like Los Angeles? W: Well, it is cleaner than I thought it would be, and there are a lot of trees, so I like it better than I thought I would. But it's huge! It's really hard to get around. The bus service is terrible, and you know, I don't like taking the underground. We had to rent a car. M: And was the weather good? W: Oh, yes, it was nice and warm in Los Angeles. M: What about San Francisco? W: The weather? It was cooler than LA, but it wasn't uncomfortable. M: Cool in San Francisco? That's surprising. W: Yeah, it surprised me a bit, too. And it was a problem because we didn't take any sweaters or anything like that, but it's always like that in August. Anyway, I loved it. It's probably the most beautiful city in the US-all those hills, the bay, and those magical old Victorian houses. M: So, you like it better than Los Angeles? W: Absolutely! And there's much more that you can see and do on foot! It's smaller than Los Angeles, so it's much easier to get around. There are lots of buses and streetcars, and of course, minibuses, too.
