A Life-Threatening Summer Shortage Led to This Side Hustle for Seniors — No Electronic Devices Required The gig does pay, of course — but for these seniors, it’s not all about the money.

The U.S. is grappling with a national lifeguard shortage this summer — and New York City is dipping into an unusual talent pool.

Four rookie lifeguards over age 64 enrolled in the “notoriously challenging training program” this summer after the Parks Department broadened its recruitment approach, The New York Times reported.

In May, the Parks Department said it had hired and certified fewer than 500 lifeguards and hoped to have 900 by the time outdoor pools opened at the end of June, per Gothamist. According to the NYT, the number stands at 800 today.

The senior lifeguards will earn more than $21 an hour, but money aside, they’re embracing the opportunity to positively impact their community — and having fun doing it.

“I love it,” 69-year-old Daniel Kalmann, who’d quit his job as a bicycle tour guide and cut back on his credit-card processing business before picking up his whistle, told the NYT. “No device on me, just looking, looking, looking.”
