A good point my sensei said to me is for example here the when Police are training there "SpeedCops" traffic division during there test they have to verbally talk whilst driving on their awareness like people ahead, time, weather, traffic light ahead, whats going on behind etc etc etc. So in other words when you are walking down the street talk to yourself what going on , the surroundings people around you etc, then after time it will become second nature... i think thats what some are trying to explain with the sixth sense. As a tip dont talk out loud when doing the walking commentry as you may end up in a padded cell LOL
