Even the hardcore gamblers will not think about gambling if it is their last day. Why would they when they will have so many important things to do.
I would remember all the people who have helped me and cared about me on that day and will send some of my money to all of them as a token of remembrance.
No one would even think of gambling in his last day. As long as she has a healthy mind, she will think of something more rewarding, like repentance, sharing, especially sharing to people in need, having fun with loved ones to give them a beautiful impression. I'm sure everyone will think of one of the things I've mentioned, or even everything, or even more. No one will think about gambling.
I have a family and my last days will be with them, all my money ( if I have some hoho ) and other possesion I will give to them. We are normal people, with families and for us that is the only way.
But about this no one will think about gambling in last days its not true, just take a look on Las Vegas for example, how many old people are gambling there? Many people are without family and close friends, and many of them found consolation in playing slots all day, or other games.
