err...you are absolutely correct about net physical force...
the individual brain is near the bottom of that spectrum..
virtually no force generated directly from the brain.
(it was brain power that drove the development of the atomic
bomb though... computational communication it seems is
mightier than the stone ax.... your personal mileage may vary.
We understand that...and thats fine.)
There are the issues of coherent high frequency emmissions
studied by NASA since the early 70's with deep space probe
experiments... some detailed in 'the secret life of plants'
by Tompkins.
In the last decade or so, first at the Univ of Arizona, Dr
Roger Penrose began quantifying these forces in measurable
mathematical terms...with external measurements confirming
these.
Currently a few dozen major universities world wide are
involved in the advance of this now known science.
The nature of ultra high frequency coherent emmisions is
almost limitless penetration as signal carriers, with almost
no force..
You might not find that research interesting because it
contradicts your limited views. ..oh well.

Throw you stone ax at will.
That regression is also studied... your personal part in that
is crucial.
