I would agree with you that one should not gamble when one is tired. I would also like to add that when a person is in a state of mind that can affect their gambling such as putting you in a rush situation, or forcing you to make a hasty decision. Because at this time, gambling is based on emotions and it can bring big losses.
Also, there's no fun or entertainment or thrill that you could really be able to feel up specially if you are tired or really that exhausted from your work. Gambling or betting isnt something that would really be that necessary for you to do so. There would really be a specific time that you would really be needing up to gamble but of course it would really be on the time that you are really that vacant and not tired or exhausted
on which same as you said that on the time that you are on such state then you would really be finding yourself that being in a rush on making those bets.
You cant really be able to think up well because you are tired which is understandable and it would really be just that right that you should really know on when to do things.
