Many people experience postural hypotension temporarily and make a full recovery. For example, some teenagers grow rapidly and their lower spine sways forward as they become thinner and taller. They generally develop postural hypotension, probably because the sway back presses on the abdominal veins, or because the rapid growth of the spine stretches those veins and impairs the flow of blood to the heart. This gives them a tendency to feel faint when they rise from the laying to the standing position, particularly when they get out of bed each morning. However as they reach adulthood their body fills out and the feature of postural hypotension ceases to be a problem. Pregnant women also tend to develop postural hypotension because the weight of the enlarging womb drags their spine forward, and also because it sits heavily on the lower abdominal veins. The tendency to faint varies throughout pregnancy depending on the weight and position of the womb, and although the symptom usually ceases after giving birth, sometimes the symptom persists in a chronic way. There are various suggestions about the cause of postural hypotension including the ideas that it is due to hormonal factors, or a disorder of the nervous system, and it is a chicken or the egg matter. i.e. Do the hormones or the nervous system abnormalities cause the weakness in blood flow, or does the weakness in blood flow put the hormonal or nervous systems into compensatory action. Nevertheless there is evidence that mechanical factors cause impairment to blood flow, and it is likely that the persistent or repetitive pooling of excessive amounts of blood in the abdominal veins stretches and damages them. That would increase their capacity permanently and result in a chronic tendency to postural hypotension where the responses of the hormonal and nervous systems would be secondary. Impairment of blood flow to the heart would produce firstly, problems during vigourous exertion (effort intolerance - where the person refuses to exert themselves suddenly or viguourously because it brings on abnormal and distressing symptoms of rapid palpitations, faintness, and dizziness), and secondly, problems with weakness in blood flow to the brain resulting in abnormal tiredness. Postural hypotension, effort intolerance, and chronic abnormal tiredness are features of The Chronic Fatigue Syndrome, but not all people with CFS have evidence of postural hypotension, so the idea that the hypotension is the cause has been the subject of debate. Nevertheless there are differences in the severity of CFS between individuals, and in the life history of patients. Sometimes CFS appears to be genetic, and other times it appears to have a very gradual and insidious origin, but typically the first bout of fatigue can be traced back to an incident, such as pregnancy, a viral illness, or chemical exposure. In such cases the original experience reached a peak of fatigue which impelled the person to take rest for months or years, during which time they gradually recovered but remained permanently impaired to a lesser degree. There are also typical examples where there were years of minor fatigue, interspersed with brief periods of more severe fatigue. It is therefore likely that the postural hypotension is a chronic latent feature which is only evident during severe cases or with the relapses. In severe cases of CFS the symptoms tend to be worse and more numerous and varied. One of the prominent symptoms is postural hypotension and the obvious indication of weakness in blood flow is the tendency to feel faint when moving from the laying to standing position, especially when getting out of bed in the morning when patients report the they have to stand up very slowly to avoid feeling faint. Other less common observations are the sense of faintness which patients report when they lean toward a desk to write, or when they lean toward the washing machine to drag clothes out, or when they lean toward an ironing board to iron clothes, or when they lean toward the kitchen sink to wash dishes. They may also feel faint and dizzy if they squat down and lean forward to clean low windows, or when they apply the brakes suddenly while driving a car and their body is thrown forward, or when they are a passenger in a car which speeds around a curve in a country road and throws their body sideways, or when they are sitting in the chair of a rotating amusement ride at a carnival. Many patients report feeling an extremely distressing form of faintness when their body is being moved up and down and sideways at all angles on a tilt table while having some types of x-ray. All of those factors have a mechanical effect on the body, and the response is often immediate, so the condition is clearly mechanical hypotension. If the veins below the midriff, or all veins leading to the heart, i.e. all of the venous system was stretched and had greater capacity, then there would be a tendency for blood to pool excessively in response to any obstruction to blood flow. Therefore if a person stood up suddenly the blood would pool below the waist in response to gravity increasing the weight of the blood, and it would tend to pool below the midriff if the person leaned forward and compressed the air in their chest, and it would pool in the legs if a woman was pregnant and the heavy womb was compressing the abdominal veins behind or the pelvic veins below, and it would pool in the extreme outer parts of the venous system if the body was subjected to any type of centrifugal force. Therefore there is evidence that mechanical factors can cause damage to the walls of the veins to produce postural hypotension which is in turn responsible for the symptoms of chronic fatigue (effort intolerance and tiredness), However, those veins would have some resilience, and therefore some ability to recover, which would explain variations in the severity of the condition at its onset, and variations in the severity between individuals, and variations in the recovery times, and it would also explain the chronic nature of some cases, and the fluctuations in the course of the condition in others.

In my late teens I obtained 3 scholarships to study Group Work at The Institute of Technology. The first was from The National Fitness Council, the second was from the State Government Department of Community Welfare, and the third, which I accepted, was from the Commonwealth Government. I completed the course of subjects which included individual, group, and social psychology, and politics, and I had interests in leadership methods, creativity, and conformity. Later, in my role as leader of the gymnastics club, I would typically stand in front and demonstrate 20 push ups, 30 toe touches, and 40 side stretches etc, for the class to follow. However, there were occasions when parents would advise me that their child had a health problem such as asthma, which could benefit from exercise, but they would show concern that too much strain could be a problem for them. I dealt with this by advising the child to do the same exercises, but not to worry about trying to keep up the same pace. I also instructed the group not to criticise him, as that would prompt him to try too hard for his own good and would discourage him from continuing. When I was about 22 I had a very large steak and vegetable meal for tea, and 10 minutes later walked into the gym and flipped into a hand spring, and felt something rip inside my belly. The incident seemed uneventful but about 2 months later I started getting an ache in my belly whenever I leaned toward my desk in my job as a clerk. This ache gradually became worse and was eventually accompanied by various other problems such a faintness, breathlessness, or dizziness whenever I leaned toward the desk, and eventually I also started to get distressing symptoms of faintness and dizziness when doing just one somersault in the gym. My doctor was unable to explain these symptoms and they were getting progressively worse so I resigned from the gymnastics club, and soon after that I resigned from work and began reading a medical dictionary at the rate of one or two words a day until I found that my symptoms were consistent with Da Costa's Syndrome. As my health had deteriorated gradually over a period of about 3 years, I decided to participate in a fitness programme with the view to gradually improving my fitness and recovering full health in a year or two. I therefore enrolled in a course at The South Australian Institute For Fitness Research and Training. My initial fitness was measured and found to be zero, as compared to a friend of mine who had an average fitness of 900, and an athlete level of 1200. Part of the programme involved jogging, and typically I could only jog slowly for about 20 yards before struggling for breath and having to rest. For example in a group of 50 people I would be running last around an oval, and for a while I had a companion. He was 40 years old, overweight and asthmatic and I told him not to worry about leaving me at the back alone, and that he should run ahead and catch up with the group which he did. As the group outleaped me two 50 year old men ran together and one said, in a voice loud enough for me to hear, "we have an excuse for being unfit because we are 50 and have spent years smoking; we are not like the youth of today (meaning me) who are unfit because of laziness". After 3 months training my fitness level rose to 350 so I increased the number of days I trained to 4 per week. On one occasion the instructor ran some relay races and I ran as fast as I could, but was not much help to the team, and then we were required to squat down and place a 5 kg medicine ball between our knees and frog hop to the end of the hall and back. After 10 yards my heart began to beat violently and I fell to the floor and crawled around on all fours feeling faint and dizzy and on the verge of collapse for about 10 minutes. It took me a week to recover from that 10 yard run. On another occasion we left the hall and ran through the streets for a change. After about 300 yards all the other runners were so far ahead that they had gone around street corners and were out of sight so I ran alone for about 20 minutes until returning to the hall 10 minutes behind everyone else. After 6 months my fitness was measured again but it was still 350 despite improvements in my speed, strength, and endurance on the ergometric cycle. (fitness level was measured by graphing pulse rate over load). During the ninth month I was training 6 nights per week but I threw knee cartilage and had to stop. About 4 years later I wrote The Posture Theory about a postural cause of various symptoms which included fatigue. The fatigue was due to postural pressure on the air in the chest which blocked blood flow and stretched the veins below, similar to the way in which a garter blocks blood flow in the leg and causes varicose veins below the garter line. However unlike varicose veins which show up on the legs, the enlargement of the main veins in the abdomen, or the whole system may not be visibly evident, but something was impairing the normal blood flow through the body and that was my estimate of the causes of exercise problems and fatigue. Shortly after that I discussed my ideas with the head of the Fitness Institute and he suggested that I run a research programme to study the problem in more detail. I was aware from the medical literature that the general view was that these patients could not or would no train and that their reluctance to participate in exercise programmes was generally attributed to a fear of exercise. Other researchers were treating the patients as if they were physically sound and expecting them to train in normal programmes with healthy people. However, I knew that the pressure to conform would make the fatigued patients run faster than their limits and cause problems, so it did not surprise me that all of them refused to run, or dropped out of the courses before results could be achieved. Therefore in order for a programme to succeed and provide improvements in health and meaningful data it would need to be designed so that fatigued patients were in a group of their own under instructions to walk or run at their own pace within their own limits, and not to be concerned about how fast others were going. The first 3 month course involved about 20 people with 6 remaining at the end. By the end of the third course about 80 people had been medically assessed and more than 12 were still training with some continuing for the entire 9 months, and one person participated in a 6 mile marathon. The fitness levels at the outset had examples at the level of 100 and 300, but there were also some at 700 or 1100 and that data confused me until some years later when I suddenly realised that there were different types of chronic fatigue syndrome (for example the low measurements would relate to exercise disorders, and the high measurements to sleep disorders) Unfortunately the writing of the data involved desk work which was aggravating my abdominal pain so when I was asked to increase the programme to include 200 participants I stopped. My health returned to tolerable levels after about 10 years but I never fully recovered. For example, every summer I would go to the beach and run about 10 paces along the sand and then hop step into a hand spring, and when I landed abruptly with my back arched and my arms outstretched I felt a rip followed by a caustic ache in my belly. I did that once every summer for at least 5 years, always with the same response and have never had a medical explanation for it. Similarly, one day I was digging in the garden and the spade struck a rock under the dirt. The sudden jolt caused a pain in my midriff which persisted for 3 months and was accompanied by severe constipation for that time. Also whenever doctors prodded my belly with their finger during medical investigations I have always felt pain when that same spot is struck, and on some occasions it has persisted for a week after. In those early years I decided to build a carport and pergola around my house. I would start digging with a post hole digger at 9.a.m. After 10 minutes the hole would be 1 foot deep but I would be breathless and dizzy and have to stop and rest for half an hour. At 11 a.m. I would start again and 10 minutes later when the hole was 18 inches deep I would have to stop and rest again. By mid afternoon through several diggiing sessions I was able to complete 1 and a half holes 3 feet deep. At 4 p.m. my neighbour would return from his full days work and dig 3 or 4 holes in an hour without having to stop and rest. Also there were times when I would go to town by bus, and sometimes I would be late so I would have to walk fast or jog to get to the bus stop on time. On one occasion I had to walk briskly, and was at my limit when I saw the bus passing across the end of the street. I then walked faster until I got around the corner and could see the last passenger getting on, so I ran, and my heart began to pound violently so I had to stop. I watched the bus driver looking at me as if I was too lazy to run and then he drove off in disgust and I had to wait in the cold and rain for the next bus. I kept feeling generally healthier as time passed so from time to time I would try to run and could go quite fast for short periods of time but there was always a problem with symptoms if I didn't keep within reasonable limits. However sometimes I got caught in situations where I was motivated to ignore those limits. For example I often go walking, sometimes up and down hills, but on one occasion I was asked to join some bush walkers. It was difficult enough to keep up the pace in the early stages but then the leader turned left up a steep hill. I puffed and panted to get to the first tree about 10 yards up and after reaching the second tree little old ladies and old men with walking sticks started to stream past me. By the time I got to the top of the hill every one else was relaxing and chatting and eating their sandwiches or having a cup of tea, and I was trying to hide my breathlessness and look as if If had gone slow because of loose shoelaces. A few years later I was able to walk quite briskly up several flights of stairs so I would do so as a form of regular exercise, instead of getting the lift. Some time after that I was walking up and down hills for exercise when I met a friend who asked me to follow him down a track to see some native flowers. When we got to the bottom there was only one way out - up - and it was steep. He kept his normal pace on the way up but after about 10 yards I was puffing and panting and my heart was pounding so I had to grab hold of a tree trunk for support. My friend looked at me from 50 yards ahead and his dog came bounding down and licked me in the face as if in a reassuring manner and then went bounding up again. The dog would disappear and come bounding back several times before I reached the top gasping for breath. In summary, the condition that I have been discussing is nowadays called The Chronic Fatigue Syndrome. I believe that the term was first used overseas in 1975, but I cannot recall when it came into general use in Australia, or when I first became aware of it. However I have been able to establish that it is measurable, that its severity varies from person to person, that it involves an exercise disorder and, or a sleep disorder, and that the condition generally responds favorably to appropriately designed exercise programmes and may even be cured. However in other cases, despite participating in exercise programmes which would make an average person extremely fit, and despite improvements in the general feeling of well being, there will remain a persistent limitation until the exact anatomical cause can be confirmed and cured.

the Australian expert on the disease, Professor Barrie Marmion, who said that Q-fever is contracted from the droplets of moisture which enter the air from the placenta of infected cows during the birth process, and Kendall Jackson had been to a cattle yard just prior to her illness, for only 20 minutes. The condition can also be contracted from contact with infected sheep or goats, and typically affects people involved in the meat industry such as auctioneers, shearers, truckies, farmers, and of course "even rural journalists".
