What people in the 24th centruy do for fun

I'm reading Kage Baker's latest book, a science-fiction novel with social satire. In this book, the 24th century's very safe, but very boring.

The governments are moral (too moral) and have banned everything that's "wrong" or "unhealthy". So there's no meat to eat. No dairy products, either, because that's considered animal creulty, too.

There's no tobacco, no alcohol, no coffee, no tea, no chocolate (they're stimulants or depressants, and drugs are bad). Being overweight will get you a hefty fine. If you don't lose weight, you're "hospitalized".

However, they do have time travel. But only the super-rich can afford it. So they take vacations back in time.

Do they visit prehistoric times to see dinosaurs? No.

Do they journey to see the splendor that was Greece, and the grandeur that was Rome? No.

They travel back to the 20th century to drink wine, eat cheese and smoke cigars.
