One of the primary reasons why people stay addicted for long is to win big. They think a big win will solve financial and all other problems in their lives.
For this very man greed was his problem £20000 is a huge sum that can afford a very lucrative business. Giving such huge amount on gambling shows his high level of greed and people of this kind can do anything just to make money not minding if it's legal or not. I wish he recovers soonest because this can cause a man to commit sucide.
but he regrets this the rest of his life , meaning he is also a small time gambler who only tries his chance of a lifetime but failed . maybe this will be remembered all the moment of his precious life how he managed to lose a amount in which can change his life for goodness if chooses the right decision.
For rich people then this wont really be a big issue but for those who do have only average income or finance status then that would really be a regrettable things in life.
This is why if you dont like to fucked up yourself then you should be aware on the risk about gambling addiction.You shouldnt tolerate on what you do have in mind.
Gambling is for entertainment and never intend to make it as a source of income because if you do then you would surely be having problems later on.
