Conclusions
My general conclusion:
Gambling is a tricky subject. At one point, if you understand the risks you are willing to take AND are of age, dare I say let them eat cake. I cannot say the same for those that are underage and not fiscally responsible for their gambling.
I do gamble, both in the casino and on sports through various books. I have understood one major thing while doing this, which my roommates hate. I bet very small. Like 20 cents. Why? It's a part of the bankroll. The bankroll is technically how much you are willing to bet. In total, it should be about 1% per bet, which is a unit. If I have 20 dollars (case), then 20 cents is about how much I will gamble because it is 1% of my active bankroll (point).
You have to be responsible. When you are easily influenced by the lights and the money you could possibly win, it is just as easy to lose sight of what happens. Bet responsibly, understand the risks, and PLEASE wait until 21 years of age.
