I appreciate the effort you went through to get the references. I have read
them all.

But (he wrote with a smile) they are not designed for my constraints: thin
soil, steep
slopes, little water, and 30 miles to the nearest Keystone paver. The
following gives an
idea of the lay of the land:

Unfortunately, the rock formations are not layer cake geology either here in
Nevada in
the basin and range province. The closest I have been able to come to
techniques is:
* http://www.merip.org/mer/mer254/water-conflict-cooperation-yemen
Unfortunately, the water rights have been stripped from the land and well
drilling is not
an option. The article plainly indicates that it wasn't much of a solution
anyway.
Somehow I need to build terrace walls that are sealed against water leakage
and that
insulate enough that cold weather won't heave the walls using only readily
available
local materials which means rocks, dirt, and pinyon pine and plenty of hand
labor. As I
am used to mining, converting some of the local limestone to quicklime has
never
been a difficult task.

Sorry for answering this late but we suffered some repeated storm damage
over the last few weeks. Including the pc blowing up due to lightning
strike.

To tell the truth I am not sure what to think of this. In the last year
alone I have seen probably ten different products being hailed as THE
solution to prolong life by at least 50 years. Dimethylglycine, telomerase,
pyrroquinoline-quinone (PPQ) are just a few of the more recent ones and they
followed older products like coQ10 (traditionally in the ubiquinone form
which is now discarded for the ubiquinol form).

Of course NAD is of serious importance in the body's biochemistry and we
could not live without it but I seriously doubt that NAD injections alone
will make much of a difference. Literally hundreds of natural chemicals are
absolutely needed to stay healthy and we better avoid all the toxins
(including EM radiation) that are everywhere these days at the same time.

I am certain that longevity promoting products are enormously hyped up these
days. I seriously wonder whether all this hype is a good thing for most
individuals and the planet and all life as a whole if it were even really
possible. I myself am a bit short of 60 and I am tired after a life full of
battle and fighting to preserve some of our natural ecosystem. I might not
mind if this world was a nicer place and more of an utopia but I can only
see more bad sh*t coming. In fact I can see it on my own doorstep now. Just
before X'mass we got seriously penalised for having too many shrubs and
trees on our farm. (Permaculture is not popular here) Probably a quarter of
our not too brilliant income gone in one swift bureaucratic pen stroke.
Of course I will keep on fighting (doing the things I feel I morally have to
do) but I am seriously not looking forward to another 60 years of the same
if that were possible by taking a magic potion.

I think there is a reason why 3 score years and ten (or a bit longer) may
not be such a bad thing. Should give you time to teach some of your
knowledge to your grandchildren if that is even possible in this ever faster
changing world and after that you are just taking up space and resources
from the new young ones of every species.

John
