As a gambler what do you think that should be the right time we suppose to leave gambling weather we are making profits or we are not making profits with gambling, because I know quite well that gambling whenever you are making profits you will wish to continue gambling unless that you run out of cash.
Don't you ask the old man personal questions because usually an old man who continues to gamble could indicate that the old man is lonely!
not far from my house, there is an old man who often plays timezone just to spend his money there, when I asked him why he often did that, he said he was very lonely because his children and grandchildren did not live with him.
Although there is no research that can explain in detail at what age you will stop gambling, environmental and psychological factors can make you continue gambling until you die, but the chances will be small if you have an intact family in your old age.
