Gabrielle Union explains how Wade is adjusting to normal life post-retirement

Post-NBA life has been an eye-opening experience for Dwyane Wade.

Gabrielle Union was a guest on "The Late Late Show with James Corden" on Wednesday night and hilariously detailed some of the things her husband is discovering for the first time now that he's no longer playing basketball.

"He's never been to a car wash, and he was like, 'I love it there!' I'm like, 'The car wash?' He's like, 'Yes!'" Union said. "He has no idea how much milk costs. He's like, 'What is that, about $20?' and I'm like, 'What kind of goat’s blood milk are you (drinking)?'"

Union also discussed Wade's excitement for an upcoming trip to the veterinarian.

Wade retired from the NBA in April after 16 seasons.
