Not something I think
is especially important, but sports betting (match fixing potential aside) seems like much more of a healthy form of gambling than most casino gambling. It doesn't have nearly as much of a potential for that addictive make a bet every few seconds high that people seem to get from slots or table games. There's a big delay between the placing of the best and the results. Obviously people can still destroy their fortunes and lives doing it, but we happily let them do that at other casino games.
