Major study was published in Lancet yesterday reporting that 25% of the people worldwide do not exercise enough in terms of their health. According to its conclusions, policies to increase population levels of physical activity need to be prioritised and scaled up urgently. I could not agree more, but on the other hand 75% of the world population are exercising quite nicely.

Particularly Finns exercise quite a lot as Finns lead the statistics amongst the western countries. Obesity and many chronic diseases are still quite common also in Finland, which makes me to ask whether even that amount of exercise that Finns do is enough to maintain or improve health? Or are these surveys, which are not relying on objective measures to determine physical activity, even misleading? How much should we actually exercise? Maybe 2-3 hours per day, as also suggested for kids?

Further, one could think based on these data that many persons are quite well-informed and health concsious as they are exercising. However, according to this study this might not be the case, but we need to continue to inform people in regards to health hazards of lack of exercise.
