Excessive or too much of every thing is very bad just as you have said and I also have said a couple of times in my previous posts, but let me point out that people are still different though, there are people who would be under the influence of alcohol and still maintain their stability and normal behavior even when they are intoxicated, but this is still not an excuse to drink excessively..
A very strange observation. People (not all) who have been drinking for a good period, become more resistant to alcohol, have better self control towards drinking. The more they drink the more responsible they are. 21 years old guy who becomes drunk after few cocktails and start to behave inappropriate vs 45 guy who wont get drunk after few cocktails, wont act wild after then; and it will even be unnoticeable that he drank alcohol. One again, not related to all, the longer person drinks alcohol, the more experienced he becomes and alcohol would harm him less.
Now gambling. Whether you are 21 or 45 years old, its still dangerous. The longer you play, the more chances to become addicted are. Young and old gamblers similarly falls of a greed victims. The older gambler gets, the harder for him to stop gambling. With alcohol, the older person gets the better he knows his limits.
You're right, in gambling, the longer we spend time, the greater the chance of addiction. I believe anyone of any age can experience this, but the rules are the same. So, if gambling is done for too long, addiction is a clear consequence. And it's clear that people who gamble for too long lack self-control. If they had good self-control, they would know when to stop, whether they were winning or losing.
Addiction to both of these things has no positive impact; both can lead to negative outcomes.
And this is why gambling activities should be reduced as much as possible. The main thing in gambling is self-control. Remember, when you can stop gambling at the right time, only then will you truly win. If someone knows how to stop and understand their limits, then it is definitely possible to avoid major losses, and by controlling themselves, the risk of addiction can also be greatly reduced. Excessive gambling will only bring nothing but harm, so it is important to limit yourself in this regard. Gambling should be as little as possible, and the purpose is only entertainment.
