I will answer first.
I will love to quit gambling when I am 42yrs because I don't want to give gambling much time and I will prefer to look for an alternative means to have fun.
My first question to you is, How old are you? How sure are you that, at the age of 42, you will stop gambling? Why do you stop gambling? Apart from the things I have already asked you, let's assume that you can do that, and that is what you know about yourself. You can do it; why don't you start now? Why wait until you're 42 years old when you can quit anytime you want?
Maybe later, at the age of 42, we can't say that you suddenly had an addiction to gambling. Do you think you can just stop gambling if you become an addict? These are just some of my questions.
