This is the first time that I’m writing 2 posts in a day. Got not other work to do 
In my 4th semester, I had taken a credit course PSY 151: Introduction to Psychology by Dr. Braj Bhushan and the course did help me to organize and better many of the concepts that I had developed by myself, in addition to introduction to many new concepts. One such thing was the concept of id, ego and superego given by Sigmund Freud. I am just proposing here a concept which I don’t know has already been said or not. The concept as to what seems to me is that as the mental age of humans increase, the id and superego merge with superego dominating largely in the newly created structure. I feel the evidence can be seen in our daily-lives in “elderly” people who simply derive pleasure if the set of principles that they have developed over their lifetime is adhered to. These set of principles may vary depending on individuals and their culture etc. e.g. In typical Indian households, most elderly people derive pleasure if they succeed in completing some religious ritual even if it is taxing on their body. It’s perhaps so because the “original ” superego dominates over the “original” ego in that new structure. Again, how soon this merger is accomplished may also perhaps vary amongst different individuals and the culture that they belong to. e.g. amongst the Jains (see this) and the Tibetans (both are sects in South-east Asia), this age might be very low, where they derive pleasures in the extremely tough rituals of the renunciation ceremony.
Would love to hear what others think about this idea.
