Excessive of anything is bad. Gambling is a social vice and a practice that can lead you to addiction. When you fail to realize that you can be addicted for merely gambling for fun, you will limit the time that you are spending on gambling. Healthy gambling should be practiced to avoid bringing shame to yourself and your family members.
You are making a point, but i find it hard to tag gambling as a social vice, social vice are harmful for the society, but gambling is a choice, and many are making life out of it, government are also making money from it. calling it social vice does not make sense to me.
The funny thing about gambling addiction is this, when you are wining from it, no body will dare call you an addict, but when gambling is dealing with one, the society will tag him as and addict. In all sphere of life,
never over do anything.
