I don’t know why but I don’t think sitting in front of my computer screen playing game is what I’ll be able to do - those gamers that are able to pull it off I don’t know why but I sure know that isn’t gonna be me; there’s an extent you play to you’ll become tired of it.
Staying so glue to the screen can be so exhausting and the side effect is blurry vision, if it doesn't affect the person sooner, it definitely will have a future effect, probably when the person has become older, by that time, they might not be able to see things clearly. Games are advised to just mind and regulate the frequency of staying glue to the screen. It boreds me to even stay on the game for so long.
People who can sit and game for a very long time are the younger ones who don't have any financial responsibilities, they have the time and energy for it. People that earn from these gamings are the exceptions, if you're getting financial benefits then it becomes a job. It is true that these games are very addictive and because of the long hours that is dedicated to it, players need to have self control. There should be limits to everything in life, overdoing can lead to health issues sooner or later so yes, discipline or control is important in gaming, gambling or whatever we do to stay happy.
