If a head were a cube and you had in each corner, to borrow some of Thalassamania's terms, Intuition, Analyses, Holism and Knowhow it could be difficult to extricate the required formula from the extremities in order to immediately execute before immediate execution is required.
However if a head is more rounded, requirements for problem solving flow more freely and are able to be correlated abstractly before a situation arises or during.
However if a ship falls on your head you will need a jack.
Every dive should have a challenge unless you don't want it to. The challenging part may be that it was performed without challenge.
I have passion for one woman and diving.
