Interesting, thanks. Hormone signalling is one of my favourite fields of study, because of an expanded component fault that has developed in vicinity of CPU. Component is part of signalling. An article on food intake regulation hormones was interesting; https://theconversation.com/article-35545 It began my sultana mode experiment. I wanted to see if I could discern different hungers. Began assessing and logging hunger. Stopped my standard response to hunger. Instead, between 9am and 6pm, ate one dried grape, nut, or berry whenever hunger began. Over several days observed was a slow increase in time before hunger began. Put this down to adaption. It proved most of my hunger was from empty stomach or bored upper intestine. Won't necessarily work for other people, due to aforementioned fault. --=20 James Cameron http://quozl.netrek.org/ --=20 http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
