Governments are spending record sums on health research, yet arguably much of what will be spent will have little immediate relevance to the health experiences of ordinary individuals. It will provide little benefit to our children and their children and have even less impact on our own health: neither during the life of current governments nor during the long line of governments to follow will the impact of that research be seen.

Young drivers are at very high risk of a crash in their first year of solo driving, and account for about 25 percent of fatal crashes due to risk factors such as inexperience, distractions, speed and fatigue.

We visit doctors for two main reasons: for help with issues that are causing us pain or discomfort, and less commonly, to prevent such conditions.

When we take a medicine, have a blood test, x-ray or a procedure, we expect that these will benefit us and that the benefits will outweigh any potential risks or dangers.

We naturally expect our doctors to guide us according to what is best for us, safest and most effective. But, how would we feel if there was no clear evidence that treatments we were given effective or truly safe?
