Would it be correct to say this start down can occur through maintaining the correct feel in the hands and making the brain aware of the correct plane line that must be traced? I'll have to go back and study the training of zone 1 (I know it is mentioned). But part of me (now) says you don't have to train your body to make the movements to pick up your keys or to reach for a cup of coffee. Thanks.

You certainly did have to train your body to pick up your keys or reach for a cup. It was just so long ago youve forgotten. Now its instinctive and you reinforce it everyday.

Watch a new baby with its rattle and toys they are training their body, hands, arms, fingers.

I know a guy who suffered a stroke and he had to retrain his body completely to do things we take for granted. One of the hardest things for him was learning to use a knife and fork again.

Unfortunately most of us were not introduced to golf at an early enough age to make the movements instinctive.
