Thanks, Volks. This chart explains everything: how dolls are born, how they grow, how they have lives, how they die?! …But I wonder about hybrid dolls. Does Frank, a Volks Yukinojo head on a Dollmore Model Doll body with Twiglimbs arms, have only 1/3 of a soul or something? The chart is silent. Noooooo !  Just when I think this hobby is all about people having fun and playing with dolls, something reminds me that there are some big cultural differences between my perceptions of dolls and other BJD owners’ perceptions.
