I am curious what is the one thing that you will never bet with? I am not talking about life because I think almost everyone will say that already but instead I am talking about other things. Like your house, your car or maybe some weird thing like your favorite shirt or the mug your father gave you. Those kinds of things. It would be interesting to see how people value different things within the metrics of gambling.
Interesting question and even more interesting is some of the answers I've read here. But... there is one I have not read and that I consider very important to me: the precious time that I dedicate to my family!
This is a very personal question and I deeply respect who said they would never gamble away an inheritance or a gift they received... everyone has something they consider most precious, and in my case, that precious asset is the time that I have and the time dedicated to the things I love. I would never enter into a gamble to give that up.
I apologize if I am being too "unrealistic" in my answer, but I am very conscious gambler, I have several limits and I could have said a lot of material things, but at this point I wanted to take the opportunity to share what I would truly never give up.
