Older gamblers, a mainstay of casinos across the U.S., are skittish about heading back to slots and blackjack tables.

Only 40% of gamblers over age 60 said they would immediately return to casinos once stay-at-home orders are lifted, a survey found. That’s much different than what gamblers under 29 are saying, nearly two-thirds of whom would return when they can. The U.S. Centers for Disease Control and Prevention has warned that adults 65 and older are of higher risk of severe illness if they’re infected with the coronavirus.
