Why we shouldn't play sport and exercise

To me that statement is just a joke because is this really happened to us we would turn into big hippos in a matter of time and wouldn’t be able to get our daily exercise.
I don’t approve of this statement because to the people who love sports would get bored very quickly from sitting around all day and they wouldn’t be as fit as they used to be.
To the people who hate playing sport and don’t get their daily exercise, they wouldn’t be able to lose the weight that they all ready had put on, when they weren’t exercise.
As well as the people who hate sport and love sport, how about the sport unions. They wouldn’t get money for doing their job. All they wouldn’t even really have to turn up at work because nobody would be playing sport and if that happened to me I would just QUIT!!!
Then we come along to the pro-sport players. Their body’s wouldn’t be used to sitting around all day, watching TV and eating junk food and for instance they would be really, really BORED!!!
So that why we should be able to play sport in the weekends and have your daily exercise and if that statement was true we would eat to much junk and be lazy, but that would prevent deaths from heart attacks and that’s very bad.
