Watching him has made me look again at the differences between these two sides of Fire. And there are great differences. I remember saying to JR Worsley that I thought there were really 6 CFs, not just 5, because Fire could be considered to consist of two, and he nodded.
So here is what my observation of Usain Bolt tells me about what I see as being typical of the Small Intestine:
1 He is able to multi-task in a way very familiar to me from my own Inner Fire abilities, and in a way no Outer Fire person would do. I realised this when I saw him chatting happily to one of the stadium volunteers standing behind him just before the 200 metre final only a minute before settling down in his blocks. He is obviously able to switch quickly from one task to the next without apparently any loss of focus. This may even be his way of concentrating more on the next thing, even if that is an Olympics Final.
2 He likes to include everybody in his joy, chatting to all his fellow competitors after the race, addressing the camera, running up to the crowd and talking to everybody there. Remember that the Small Intestine is the closest official to the Heart, and it wants to help the Heart express joy, particularly at these very intense moments. Contrast this with Jessica Innes drawing her joy back into herself when she won, and her quiet self-absorption throughout the heptathlon. (I think she is probably Metal, so quiet and self-contained.)
3 He has great awareness of what is going on all around him, seeing exactly which camera is on him, responding quickly with a joke and a smile when he knows the world is looking at him. He watches everybody and everything all the time, as though using his Small Intestine’s ability to sort so that it can send the right information on to the Heart.
