Yes, I admit that couple of the later posts were completely off-topic here in this thread, but since I found the discussion very interesting too, I did not resist participating in it. In fact, I agree that this kind of information would be much beter placed in another thread, subforum, or a category, but unfortunately an appropriate sub-forum is still missing on DB. Maybe now, when you are a moderator, Sanso, you could help tp create a new category for physiologic discussions here on DB. In fact, I'd very much welcome a whole new section (perhaps under General Freediving) that would be dedicated to science, with several sub-forums for physilogy, biology, physics, atronomics/cosmology, computer science, etc - in past there were so many interesting topics here on DB concerning these topics, but they got very quickly lost in the general freediving or beach bar sections under the daily load of "chit-chat" (Jorg's expression) type of posts who are fun, but have no informative value.
This is just a GREAT idea there, I couldn't agree more!
