I didn't really want to go there before, because it becomes a different situation when someone who has no emotions due to a disorder or something causes that. My point here is as normal humans (sorry in advance, not those who were born or certain events that make them special from other normal humans).
Of course if I want to get into that realm, then my opinion on what I said earlier will be debatable.
I'm sure you understand my point.
I had a friend like that, he made insane amount of money from trading, zero emotions at all when dealing with millions of dollars that can be gone in a second, apparently that helps. When gambling though, if you have no emotions then there is no need to gamble, because it's all about getting emotions back.
Our lives are a bit boring, maybe not yours but a ton of people wake up, shower, go to work, come back, watch something, eat, watch some more, sleep. Gambling is a way out of that, you win some and you lose some, usually you lose more than you win, but at least you feel something. The online gambling world is spreading like a pandemic, it's everywhere and it's literally hundreds of millions of people now, that's a huge number.
