Most people can enjoy things that could harm them if done in excess without a problem, it is just that the cases of the people that cannot do it are so prominent and impossible to ignore, that it may seem as if this could happen to anyone.
But this is not really true, most of those that become addicted and suffered negative consequences had a predisposition to it already, so as long as you do not have it then you should be able to gamble without suffering any major setback.
If someone engages in excessive gambling activities, of course over time he will feel uncomfortable because excessive activity is not in accordance with our abilities and the results will not be satisfactory for us but will be a matter of regret.
Yes, gamblers who are addicted will certainly feel satisfied because just by gambling they get pleasure even though they often end up losing, but for gamblers who are not yet addicted, this is a problem for them.
