Have to seriously disagree with that. Don't know of any scientific studies, but from what I've seen, sedentary people are far more likely to suffer from most of these problems than those who are athletic.
There is a difference between those that sit in an office. Those that keep temselves fit and those that partake in contact professional sport. The injuries sustained in those type of employment sport comes home to roost when age starts taking its toll.
Does not need a sientific study, all one has to do is look around the injuries sustained from Rugby is all the evidence one should need. Knees, shoulders, broken necks backs, heart. These are all muscle and skeletal damage that come home to roost. Arthritis also effects joints that have suffered injury when young.
I read a while ago many athletes have suffered minor heart damage through over exertion, if correct that may also come home to roost later in life. That was information given to me from my heart specialist.
As for living a life of activity. That does not gurantee fitness later in life. I have a hip problem caused by my past employment which involved being strapped to a floor sanding machine.
I would wager if a study was done, and honestly, on sport and its long term effects we would be sitting infront of the TV more and would not be riding horses. The largest claims on the accident insurance and hospital services in my country is sport related.
God help us if the health and safety people get there fingers into horse riding. We would be wearing armour like motorbike riders, helmets all the time, super glue to make sure we did not fall out of the saddle. The horse would have to pass an inspection to make sure it had the right attitude for the type of riding we get involved in, and also a tube into a vein so if it got out of hand we could adminster a seditive to calm it.
Sorry James I disagree with you but enjoy the debate. Horse riding is considered a dangerous pass time/sport/hobby. As is going to war.
I did not have much else to do tonight just sitting around willing it to rain.
