Hobbies, addictions and habits, it's not surprising that if you go to a land-based casino, we will find many people who are elderly, in fact, as the OP said, some of them use wheelchairs, that's what is seen in land-based casinos, what is strange is not the elderly, but the grandmothers found in land-based casinos.

Those who are elderly cannot throw away or eliminate their habit of gambling, as long as life is in their body their gambling habit cannot be lost, things like that are often seen by those who have wealth.

That's the world of gambling, once someone has mastered it, gambling no longer wants to leave that person's body, even though they are old.
