If it were fostered and promoted and recognized in the first place - and systematically in children - we would be at over 80 % practitioners - my hypothesis
Yes, it would be very important that children could keep their natural abilities. LDing could be promoted on school activities, like asking children to visit some place in their dreams and then ask them to write a text or draw something. I have felt very humble listening to some kids's LDs, and one immediately learned to LD without any technique, ahh he even told me he doesn't know what to do, because he was lucid a like an hour. When i see him he always has some interesting stuff to say, including advanced dream control techs, like time dilation, stability...
