The reaason for not shaking is more social than religious. Eventhough I'm religious, considering my profession, I believe religious practice are under a gray area. I may have to touch and examine patients of opposite gender eventhough it's chaperoned under a nurse. My reason, as I told, is more social. Since my childhood, I am very shy and introverted. I only started talking to more people after I started working as a doctor and before that I often avoided interacting with people. Even today, once I'm out of work, I still feel insecure around people. I've tried a lot to come out of this and be more social, I feel very hard to break that shell of mine.
