text:  This vitamin D you're talking about is inside this brain medicine, these vitamins you guys give. A human being can get all the vitamins they need in 20 minutes a day outside in the sunlight. If someone's going to stay inside in their home all day in a dark room and depressed or whatever else, watch TV or anything without wasting their time, they're going to definitely be deficient in vitamin D, so they need to use the vitamin. However, if someone's down or about and low down in their feelings or whatever else, going outside is a very key element, and a lot of people are afraid of it.
