Your replies have been so helpful! It is an interest that has grown very strong recently and has slowly grown over a long period before that, and you have all helped me look more clearly at my doubts and think of ways to test things out first and take it step by step. It’s not true that it doesn’t interest me or I wouldn’t be here talking about it. I’ve already spent a lot of time thinking and researching and needed to find my way through my doubts. Thanks!!
