A study done at Oxford University by a professor of evolutionary psychology have shown that laughter causes the release of natural opiates. After watching funny videos people's pain thresholds went up but not if they viewed factual documentaries. We tend to view laughter as an emotion but it is in fact a form of exercise and by doing this type of exercise where we perform repeated forceful exhalation of air from our lungs by using the diaphragm we increase the production of endorphins which in turn will increase the pleasure of being made to laugh

Thoughts on assisted dying
This article was written by a friend of mine, Dr Duncan Stewart
Three elderly clerics are discussing the point at which Life
begins. The Anglican, slightly
pompously, begins with “As soon as a newborn baby cries, Life has
started.” “Oh, No” responds the Catholic
priest, who presumably has no firsthand experience of conception, “Life begins
much earlier. It starts when the sperm fuses with the egg” They both look at
the Rabbi who strokes his beard and slowly announces “In my opinion Life begins
when the children leave home and the dog dies.” A very important debate about
the end of life, with some equally whimsical moments, is swirling around the
corridors and leather benches of our Parliament . The supporters of Assisted Dying
are making progress in spite of sustained opposition to a change in our laws
from senior religious figures whose predecessors obstructed the passing of more
progressive social legislation than any group except the aristocracy.
It is generally agreed that life has ended and the undertaker can
confidently be called when the heart beats for the last time .There is less agreement about those “not quite dead” states in which death
is both inevitable and imminent , as
when other organs like the liver and kidneys fail or that “Old man’s
friend ” pneumonia intervenes. Fortunately, in these forms of terminal illness,
pain is not a prominent symptom so fewer ethical problems arise. We all fear
uncontrolled pain but sufficient doses of
opiate drugs can control any pain and if the dose required causes a coma
that is only ended by death , so be it. But what if you have a condition which
is not only painful and terminal but has deprived you of speech, movement and
continence? What then? If you could somehow summon effective help in such a
situation, you would not request the presence a homeopath nor a priest, you
require the help of doctor with a syringe driver full of Morphine .
I can understand the
importance to a believer in an
afterlife of being reassured of this by
the his priest but we live in an increasingly secular society so why does religious thinking still dominate this
territory? The opportunity to rob your neighbour, murder his noisy children or
seduce his wife, has now passed. In any
case why do God’s earthly representatives object to doctors relieving pain and
anguish when all the other
parties involved ; the patient, physician and relatives , have all agreed after much
careful debate that to end life
remains the only humane act? I refuse to
accept that anyone’s god is going to be seriously offended if a few souls
smelling strongly of barbiturates reach him a few days ahead of schedule.
For myself, I imagine my final day lying in a comfortable bed
surrounded by friends and family sorry to see me go but thinking, perfectly
reasonably, about my last will and testament.
As life slips gently away I
will be reviewing my few successes , my many more numerous acts of
timidity and unkindness and finally trying to compose a witty last utterance. Maybe.
Forget the rising cost of living and ponder on the cost of prolonged
dying. I intend to
vote for whoever wants to repopulate the House of Lords and legalize
Assisted Dying and to give more
generously to our 2 superb local hospices, The Martlets and The Beacon to whose
running costs our parsimonious government contributes only a miserly 30%. I will also check that my having made a
Living Will, which lawyers refer to as an Advance Decision, is known to my family,
solicitor and GP. This simply states one’s wish not to be resuscitated where
this is clearly inappropriate and while it cannot override existing legislation
it may help all who participate in that decision. You can download the
paperwork very simply. I will also dust off my organ donor’s card in case any
of my organs have a bit more mileage left in them.
Our 3 clerics would all have
accepted the Paediatricians’ assertion that the first 12 hours of life,
whenever it starts, are the most dangerous; but they are not as hazardous and
uncertain as the last 12. RIP

Physical activity should be done in moderation to look after your joints
People who engage in excessive
high-intensity physical activity and those who do very little physical activity
might be damaging their knee cartilage, according to research presented at the
Radiological Society of North America 98th Scientific Assembly and Annual
Meeting.
The loss of cartilage is progressive
and irreversible. "Once the cartilage is gone, it is gone for good and
cannot be recovered," said senior author Thomas M. Link, MD, PhD. "This is why it is so important for
people to do physical activity in moderation and to use safe practices when
they do sports such as running and playing tennis. He also said "I have seen people in their 20s
who have completely destroyed their cartilage surface and I wonder what is
going to happen to them. They are going to live another 50 or 60 years. They
cannot walk on bone, so they will need a total joint replacement, perhaps
several, over their lifetime. Each time the bone gets thinner and weaker
because bone does not react well to total joint replacement. This is going to
become a serious problem," he said "People need to learn how to protect
their joints when they do physical activities, he said. "People should be
active, but they should make sure they're exercising in a safe way and not
destroying their joints."

Packing up smoking
Patients with spinal disorders who quit smoking may experience substantial improvements in back pain
Caleb Behrend, MD, from the University of Rochester Medical Center in New York, and colleagues present their findings in an article published in the December issue of the Journal of Bone & Joint Surgery.
The authors mention that smoking has been identified as a modifiable risk factor for chronic pain disorders. "Furthermore, with regard to chronic pain disorders, smokers have reported an increased magnitude of pain when compared with nonsmokers," the authors write.
In the study, the authors reviewed questionnaires for 5333 patients . Patient-reported pain scores were assessed using a visual analog scale (VAS) of 1 being the least pain and 10 being the worst.
Compared with never-smokers, current smokers reported significantly greater pain scores at the latest follow-up ; mean VAS score, 4.49.
Patients who quit smoking reported significantly greater improvements compared with current smokers in worst weekly pain.
In addition, nearly 2-fold more patients who quit smoking reported a more than 30% decrease in worst pain than current smokers (32.0% vs 16.6%), and never-smokers reported a greater mean improvement in disability.
It was concluded that smoking cessation programs are needed to improve chronic pain among patients with spinal conditions.

Taking Glucosamine, Chondroitin, and Fish Oil may reduce inflammation
Regular use of glucosamine, chondroitin, or fish oil supplements reduces high-sensitivity C-reactive protein (hs-CRP) by 16% to 22%, a marker of inflammation, according to a new study. Inflammation is now recognized as a factor in cancer and cardiovascular disease as well as many rheumatoid diseases. A number of over-the-counter dietary supplements are being marketed for the purpose of reducing inflammation, but data supporting the claims are limited.
In an article, published online in the American Journal of Epidemiology, the researchers report that regular use of glucosamine, chondroitin, or fish oil significantly reduced serum hs-CRP.
In participants who regularly used a supplement, the researchers found hs-CRP reductions of 17% with glucosamine, 22% with chondroitin, and 16% with fish oil compared with participants who did not take the supplements. The analyses were adjusted for age, gender, race, smoking history, and body mass index.
Effects Limited to Women
The anti-inflammatory effects of glucosamine and chondroitin in the overall study population were driven by effects in women. Effects in men were small and nonsignificant.
The supplements methylsulfonylmethane, garlic, ginkgo biloba, saw palmetto, and pycnogenol were not associated with reduced inflammation.

A study of the effects on mortality of muscle strength in young people
CLINICAL CONTEXT
Although multiple studies have focused on the relationship between aerobic fitness and the risk for mortality, less research has been conducted on the possible association between muscle strength and mortality outcomes. Ruiz and colleagues addressed this issue in a study published in the July 1, 2008, issue of the BMJ. They found that higher muscle strength in the legs and chest among men between 20 and 80 years old was associated with reduced rates of overall mortality and cancer mortality. After adjustment for the degree of cardiorespiratory fitness, muscle strength did not significantly affect the risk for cardiovascular mortality.
Young adults have a very different epidemiology of mortality vs middle-aged and older adults. The current study by Ortega and colleagues evaluates the effect of muscular strength on the risk for early mortality among young people.
STUDY SYNOPSIS AND PERSPECTIVE
It is well known that hypertension and high body mass index during adolescence are associated with premature mortality. Now, a long-term prospective study of more than a million Swedish adolescents has turned up yet another risk factor: low levels of muscular strength.
The study was published online November 20 in the BMJ.
The authors of the study, led by Francisco Ortega, point out that muscle strength in adulthood has been linked to all-cause and cardiovascular mortality in adults. Until now, however, similar data have been lacking in adolescents.
Similarly, they say, better cardiorespiratory fitness is associated with better mental health in adults, but there has been scant evidence whether muscle strength at any age is associated with future mental health and suicide mortality.
"This study provides strong evidence that a low level of muscular strength in late adolescence, as measured by knee extension and handgrip strength tests, is associated with all cause premature mortality to a similar extent as classic risk factors such as body mass index or blood pressure," the researchers write.
Ortega and colleagues followed up 1,142,599 young men aged between 16 and 19 years who were evaluated for service in the Swedish military. During a median follow-up of 24 years, the researchers assessed the extent to which muscle strength in adolescence was associated with all-cause premature mortality, which they defined as death before age 55 years.
Participants who scored high on the knee extension and handgrip muscle strength tests had a 20% to 35% lower risk for death from any cause and from cardiovascular disease compared with those who scored low on the strength tests. Further, the researchers note, those differences were independent of body mass index or blood pressure status.
Ortega and his colleagues conclude, "Low muscular strength should be considered an emerging risk factor for major causes of death in young adulthood."

STUDY HIGHLIGHTS
- Study data were drawn from Swedish military conscripts registered between 1951 and 1976. Researchers focused on individuals who were 16 to 19 years old at the time of baseline testing.
- Participants also completed strength testing at baseline, including handgrip, elbow flexion, and knee extension power.
- Participants were observed until the time of death or immigration away from Sweden. Death registers were used to follow the main study outcome of early mortality, which was defined as death before age 50 years.
- Researchers focused on the relationship between muscle strength at baseline and mortality outcomes, with particular attention to death from suicide, cardiovascular disease, and cancer.
- The study outcomes were adjusted for year of birth and conscription office.
- 1,142,599 men provided data for study analysis. The mean follow-up period was 24.2 years.
- 26,145 men (2.3% of the study sample) died during follow-up. Suicide and unintentional injuries comprised nearly half of the deaths recorded. Cardiovascular disease was responsible for 7.8% of deaths, and cancer accounted for 14.9% of deaths.
- Overall, higher levels of muscle strength reduced the risks for early overall mortality and cardiovascular mortality by 20% to 35%, but strength did not affect the risk for cancer mortality.
- A mortality benefit of improved muscle strength was evident regardless of body mass index at baseline.

Keep your heart healthy with the BBC
Activity for a healthy heart
Prevention is always better than cure. This section outlines how regular exercise can give you a healthier heart and how relaxing can help reduce stress levels.
- Healthy heart
- Active heart
- Aerobic exercise
- Resistance training
- Flexibility
- Where to exercise
- Safety first
Healthy heart
Educating people about the risk factors of heart disease and persuading them to adopt a healthier lifestyle can have an impact on the number of people dying from heart disease and stroke.
Encouraging people to stop smoking, drink less, eat better and exercise regularly are particularly important. Doctors can help by asking about smoking habits and encouraging patients to use nicotine replacement treatment, such as nicotine patches.
Even if you've already been diagnosed with heart disease, making lifestyle changes can help you live a longer, healthier and more enjoyable life.
Active heart
Being active is essential for a healthy heart for the simple reason that your heart is a muscle. Even if you haven't been active for some time, your heart can become stronger so it's able to pump more efficiently, giving you more stamina and greater energy. Becoming more active will also improve the ability of your body's tissues to extract oxygen from your blood, help you maintain healthy levels of blood fats and speed your metabolism.
If you are overweight, you're 80 per cent more at risk of heart disease. The best way to control your weight is to eat a healthy diet and take regular exercise.
Three types of exercise are vital for all-round fitness: aerobic, resistance training and flexibility.
Aerobic exercise
Aerobic, or cardiovascular, exercise is particularly important in the prevention of coronary heart disease. This is any kind of activity that increases your breathing rate and gets you breathing more deeply. These activities include walking, running, swimming, dancing or any of the aerobic (cardiovascular) machines at the gym, such as the rowing machine, treadmill, stepper or elliptical trainer.
These are designed to increase the strength of your heart muscle by improving your body's ability to extract oxygen from the blood and transport it to the rest of the body. Aerobic exercise also enhances your body's ability to use oxygen efficiently and to burn (or metabolise) fats and carbohydrates for energy.
Resistance training
Resistance training helps to make your muscles stronger, strengthens your bones and protects your joints from the risk of injury.
This type of exercise can involve the use of free weights and weights machines such as those found in the gym, or any kind of activity in which you load your muscles. For example, carrying heavy shopping bags or exercises such as press-ups, lunges and squats, and some of the yoga exercises in which you use your body weight, are all good for resistance.
Resistance training doesn't increase the fitness of your heart like aerobic exercise, but it can help to control your weight because muscular tissue burns more calories than fat.
This type of exercise isn't recommended for people with uncontrolled high blood pressure or heart disease, so if you are affected by those conditions, check with your doctor.
Flexibility
Stretching helps relax and lengthen your muscles, encourages improved blood flow, and helps to keep you supple so you can move more easily. Experts say it's good to stretch for five to 10 minutes every day.
There are a number of simple stretches you can find in virtually any book about exercise, or be taught by the instructor at the gym.
If you want more organised stretching, yoga and Pilates are safe and gentle for people with heart problems, as they help calm the mind and body and reduce stress. That said, there may still be some exercises or postures that are not recommended if you have heart disease, so check with your doctor first and tell your instructor if you have high blood pressure or heart disease.
Where to exercise
There's no need to join a gym or take part in organised sport, unless you want to. Simply incorporating more activity into your daily life and doing activities such as walking, gardening and cycling can be just as effective as a structured exercise programme.
Your aim is to be moderately active for 30 minutes most days of the week. If you find it hard to fit this into your life, split it up into shorter periods. You should feel that your heart rate is increasing and that you're breathing more deeply and frequently. You should be able to walk and talk at the same time - if you can't, the activity is too strenuous.
Safety first
If you experience any or all of the following, stop exercising immediately and consult your doctor:
- Chest pain
- Dizziness, light-headedness or confusion
- Nausea or vomiting
- Cramp-like pains in the legs (intermittent claudication)
- Pale or bluish skin tone
- Breathlessness lasting for more than 10 minutes
- Palpitations (rapid or irregular heart beat).
- Continued fatigue (lasting for 24 hours or more)
- Fluid retention (swollen ankles, sudden weight gain)

On your bike..
Just read an interesting article on why riding a bike is pretty special. The rite of passage from little kid to big kid when you get your first proper bike, dump the stabilisers and whizz away.
Interesting work by researchers in the Netherlands showed that riding a bike can tell us stuff about the brain and how it functions. Patients suffering with Parkinson's disease are often affected with tremors, involuntary muscle movements and can have problems with balance, co ordination and limb control. One such patient, a 58 year old man had "gait freezing"where he was incapable of normal walking, needed visual guides to help him step one foot in front of the other and often lost his balance so that he needed to sit in his wheelchair. Yet put him on a cycle and he was able to ride it with out any problems. The video is available on YouTube and it shows him initially shuffling down a corridor with help and after a few steps he stumbles and falls. The second video shows him riding a bike with no signs of tremor pedaling at a consistent pace with perfect balance and coordination then he gets off the bike and he is once more unable to walk. This phenomenon is called kinesia paradoxia and the study of which may lead on to different forms of physiotherapy treatment. Further research is going on to study how the human is able to ride, how the cyclist interacts with the bike and the environment and all the requirements that are need to make what is a very complicated procedure look so simple
