15 things successful people do during their lunch break

Do you typically spend your lunch hour scarfing down an unhealthy meal at your desk? Maybe you run out for a quick bite but keep your eyes glued to your smartphone. Or perhaps you just skip lunch altogether.

Experts say your lunch hour is critical for keeping your productivity and energy levels up. Working or rushing through it can be detrimental to your success.

"Your lunch hour is your chance to get refocused, reenergized, and refueled (literally) for the rest of your day," says Michael Kerr, an international business speaker and author of "The Humor Advantage.
