If they did not keep track of their records, it is possible that they would simply set aside a limited amount of money for gambling in order to keep their own losses under control. It's depressing to know how much money you've lost over the course of your gambling career, but it could be a sign that you need to stop gambling or put some restrictions on how much you gamble.
And that is one of the massive advantages of record keeping, if you look at the amount of money you have spent gambling over the years and you cringe about it and you think you have lost a lot of money, then that is a clear sign that you should slow down for a bit or even stop gambling for some time, as in my particular case I do know that number, or at least my best estimation of that number, and I do not have any problem with the money I have lost over the years.
It is true that recording betting results in the last few months can provide benefits to better regulate the gambling activities they carry out and can enable them to have limits or control so as not to experience bigger losses like those in the records.
But another impact is the emergence of feeling of disappointment with what one has done because one has spent very large amount of money and even the winnings as return do not reach half of the amount that was used during that time.
All actions always have good and bad and it depends on us how we think and respond to each action.
But so far I don't think many gamblers have recorded their gambling history because it takes time and is little more complicated by taking into account every bet that has been made over several months or several years.
