Interesting point Millie210 .....there are definitely some warm and fuzzies connected with things from our childhood. It is natural to be drawn to friends, family, places and things that remind us of those early times. I can see the primal / survival part of it too. We might form stronger attachments early on to what helped us survive or what we think helped us survive.
You could make some jokes from that premise. Like sticking to the JW religion from birth is like continuing to consume breast milk or Gerber baby food as an adult.
undercover - I agree wholeheartedly. I wrote a post about a similar topic here.
