Hi, guys. Hello. How are you? Are you volunteering? Volunteering more. Yes? No? Are you being more grateful? No? Yes? Did you practice it? Did you talk to someone, send an email? Yes? No? Okay. So before I start the class today, who knows what the topic is for today's class? Do you know which class you're in right now? This is Life 101. Yes. You're in the right class. Before we start the lecture today, I promised one of your classmates to share a joke with you, but you have to promise me to laugh. Oh, great. This was an exercise. Wow. From now on, I'm not going to even say anything or share a joke. I just say laugh. So laugh. Oh, very good. I told her that I'm going to share this, it's not actually a joke, it's a real story. I will share that very quickly and then we start. When I was running the cholesterol clinic at the UCI Medical Center, I was seeing patients in that clinic and it was a pretty busy clinic. We had patients, we had physicians, we had attending physicians, we had medical students. We had a very large patient population who did not speak English. In that patient population, we had Hispanic patients, we had Vietnamese patients, we had Iranian patients, you name it, so they didn't speak any English. But we had a very good translation service. We still do. We have a translation service for patient care related issues at the UCI Medical Center. The translator come to your clinic or to the patient bedside and help the health care providers to translate. In that clinic, I had two Vietnamese patients with very complicated lipid profile. They both had heart disease and they had high cholesterol. So I was taking care of them. My nurse would ask me if I needed a translator for them and they didn't speak any English. I would say no, and I never needed a translator. We were fine. What are you guys thinking by now? Our Vietnamese students are like, oh my gosh, she speaks Vietnamese and we didn't know that. She understood everything that we said. Let me finish the story. Then one day, I got a call, I was paged to report to the emergency room because a patient was admitted in a very severe situation, the patient had a heart attack. There was no family member with the patient, and the patient couldn't speak any English and the patient was Vietnamese. I got a page to report to the emergency department to translate for that patient. I said, why are you calling me? Then they said, "Dr. Jafari, don't you speak Vietnamese?" I said no. They said, but when Mr. so and so came to the clinic, you never asked for the translator. I said no, I didn't because they spoke very good French and we just spoke in French. That's why I didn't need the Vietnamese translation. That was my joke guys, so now you can laugh. Are you really laughing or you're faking it? Faking it? No laughing? Oh, good. You two are laughing? Okay. These are my best friend forever right now in the class. They are laughing. That was my joke. Are you happy now? Yeah. Okay, great. All right. Now, we're going to start the class. For those of you who do not remember, let it be surprise, is that we are going to talk about bad drugs on college campuses. It's like, oh no, she's going to preach, she is going to lecture. We don't want to hear it. But guess what? You are my captive audience for another 45 minutes. You have no choice but participating and listening. I shared some of my slides and also the topic of today's lecture with some of our graduate and undergrad students. Unanimously, they told me that by the time that you finish this presentation, you are not going to be a very popular person. I am going to make a confession here. That's not what I'm looking for. My job as a professor, as somebody who is teaching this course, is to present data, to present fact, and to present science. You are older than 18, so I am sure that you can take the information, see if it applies to you, see if you like it, if it makes sense, applied or not applied. But my job is really to present the truth and nothing but the truth. I am not here to present alternative facts. These are facts. Before I start this lecture, I have to tell you that I spent a lot of time making these slides. This lecture has nothing to do with whatever I have been presenting for the past six years in this class. I have to really, really think about every single slide that you're going to see in this presentation because every slide hopefully has a meaning and hopefully can help you to make decisions and inspire you to adopt a healthier lifestyle.
