I think sports are a very good way to keep people away from drugs and alcohol. And also reflects that a nation with many people making sports, is a nation healthy and worried about their future and quality of life.
To encourage others to do sports, I'd tell them that it doesn't exist a better way of feeling comfortable with ourselfs, that making something for your body and your health. There's so many sports to do, and everyday there are more chances to practice them. So if you don’t do a sport, is just a cheap excuse.
About “rodeo a la chilena” I think is not an sport. Yes, is popular, but it can't be called an sport. I have seen in many rodeos in the Central Region of Chile, that the "cowboys" which practice this "popular game", drink alcohol before going on "stage", and what can we say about the damage that cows suffer when they get hited by horses. Fanatics of this "popular game" says that there is no damage caused to the animals, but the truth is other: they end up with fractures and internal bleeding that can send them to death. If people whant to practice "rodeo", they are probably on their “right”, but it should be modified for protect animals involved on this practice.
Anyway, just keep your body moving and in permanent activity, is the better way to avoid obesity and especially to avoid cardiac problems.
