If you are BORN in to something, you have not really CHOSEN it for yourself. Amirite?
Basically, if you are born in to a family that farms, and they raise you to be a farmer, you did not necessarily have any say or choice about your future. This happens quite a bit in our country. Or if you are born in to an affluent family, the tendency is for you to become a doctor, lawyer, or some other lucrative career. The same applies to religion. If you are born in to a family that practices a certain faith or denomination, many grow up and follow the status or tradition of the family - never looking outside that immediate circle or sphere of exposure.
If a person is perfectly happy and content doing so, that is fine. But did THEY personally ever really choose those things for themselves?
