One must first define the meaning of religion and whether it is something that fits in our lives.
A religion is a philosophy based on spiritual beliefs. It aims to dictate a canon that would help to heal the spiritual side of the individual and, eventually, it will permeate into the dynamics of life.
This being said, a religion may only be important to those who a) believe in that there is such a thing as spiritual needs, and b) need some form of moral or emotional support to enhance their lives.
If you are one of those two types of persons, then practicing some form of religion may help you find ways to (for example) meditate, pray, practice your patience, strengthen your levels of tolerance to adversity, help you understand the nature of people.
Therefore, being that having a religion is a choice, perhaps it is a good choice for those who need to learn ways to understand their lives, and that of others.
