@Olivier5,
We are all creatures of habit. Often times, we do things without giving it much thought, because we've done it so often, critical analysis isn't needed.
What is also interesting is something I learned many decades ago. People spend more time deciding on buying a tv or a car than they do planning for their retirement.
We make our decisions based on our experience and perceptions and how past decisions turned out. The choices we make are based on 'guesses,' but we base it on past experience and understanding. It's 'our' guess, and we're the one who decides when, where, what, and why. We don't need to explain it to others why we made the choice we made. It's our reality.
Choosing to be religious or a drunk doesn't need to be explained to anyone demanding to know. It's our guess, and we're the ones who will get the reward or pay the consequences. It's none of their damn .........
