Perhaps this player died because he did not lead a healthy lifestyle. A real gambler can play for more than 12 hours a day, that is, he is completely immersed in the gameplay.
This is very harmful to the heart. In general, a person should walk at least 10 kilometers a day (and preferably 20 kilometers or more). Also, in the morning, it is imperative to do physical exercises and wash with cold water. You also need to eat right - eat a lot of fiber, fruits, meat, fish, nuts and vegetables.
All this will reduce the risk of an unexpected heart attack.
Perhaps this player also had a congenital heart problem. Gambling is good entertainment, but you can’t consider it a source of income. After all, excessive expectations increase a person’s stress level and can lead to such tragic events.
It is clear that this player does have a weak heart, and he could be lacking exercise or have an unhealthy lifestyle as you said, because I think it is impossible because of gambling winnings that someone can die and hang, this is not because of gambling, but because he already has a weak heart.
Even without gambling, when he feels the tension that makes him surprised and feels incredulous, he will definitely experience the same thing like that, it's just that maybe because this victory surprised him too that made him like that.
