second largest increase, was 19.2% +/- 16.3%. Compared with the rest of the
brain, an excessive increase of blood flow during acute exposure to hypoxia is
found in the hypothalamus. The functional implications are at present unclear.
Further studies of this finding should elucidate its meaning and especially focus
on a potential association with the symptoms of acute mountain sickness.
Final Note on Held-Breath Underwater Swimming: In order to achieve maximum results
from this exercise, you should practice this exercise daily at least over a three-week span.
Occasional swimming does not have much effect, as the Carotid arteries rebound.

Exercise 20: One Way to Improve Eye Coordination
This is another low-cost or no-cost way to improve how well your eyes can work together. You
need three pieces of string, two short sticks (these can be ice cream sticks) and a golf ball or
large marble plus some tape. The three lengths of string are: one of them about three feet; one
of them about two feet; and one of them about one foot in length. The whole assemblage will
fasten to a nail head in either your ceiling or overhead doorway.
The three-foot string attaches to your overhead nail head. The other end attaches to one of
those short sticks, close to but not quite on the center. The two-foot string: one end of that
attaches near but not quite on to the center of that first short stick. The other end of that two-
foot string attaches to your other short stick, near but not quite at the center. From near the
center of that second stick, attach the third, shortest string. To the other end of that shortest
string, loop your golf ball or large marble and secure with tape.
Position yourself two to four feet away from that whole hanging ensemble. Set it gently
swinging. Its motions should be complex, nearly unpredictable. Keep your eyes as nearly
completely as possible on that irregularly moving marble or golf ball. For two to three minutes
at a time so you don t tire, often through the day or at least three times a day.
Exercise 21: Looking into Eye Congestion
You might look to a nutrition counselor or some of the books on the subject for a decongestant
diet that will bring down your overall levels of congestion. In general, increasing the level of raw
fruits and raw vegetables in your diet can help this, and drinking a fair amount of relatively
pure water (some sources say up to eight full glasses of water a day, but I find that a bit heroic).
Supplementing with Vitamin C is also reputed to help bring down levels of congestion. I am
neither a physician nor a nutritionist so you need to check other sources on this matter. Higher
levels of physical activity (here comes that ping pong again, or maybe some of those aerobics)
can go a long way to reducing congestion generally, not only around your eyes.
Also, an allergist can help you discover some elements in your environment to which you have
some sort of chronic allergy, or trace allergies in some of the food you eat, which could be the
source of that congestion in and around your eyes or even directly in your brain. If you have
good days and bad days, look to an allergist as one possible way to make a major positive
difference in your life and level of abilities.
Generally you have three ways to improve how well your eyes track together, which in turn
affects how well much of your life works: one is through exercise and training, such as with
ping pong and/or that hanging-swinging contraption; one is through reducing congestion in and
around your eyes; and one is professionally, through working with a developmental or
behavioral optometrist or ophthalmologist.

Win s Recommendations
To this point, to review what you have learned, Win strongly recommends that you perform the
following practices:
" Constantly, ongoing, many times a day, add to your Portable Memory Bank.
" Flick-Gazing for one to three minutes at a time is a very good daily practice. The first few
days, probably two to three times a day.
" Seeing once in awhile just how richly and colorfully you can describe something, how
much detail you can give it.
