However, not everyone enjoys gambling or casinos, so many people are indifferent to betting. But if it were me, I would definitely do it because it's quite enjoyable. If I had ample time, I would certainly be more aggressive about it.
Enjoying gambling is not for everyone. Just because you work in sports and you closely interact with the athletes and other personnel in the industry does not make you develop any interest in betting on the sport. But I am sure that they are already betting unofficially with the way they make predictions so why not make it official and make some money?
