00-year-old Leads Exercise Classes, Checks In On Facebook.

A 100-year-old exercise instructor says the secret to longevity is an attitude of gratitude.

St. Paul resident Lauretta Taggert celebrated her triple-digit birthday this week.

Taggert says she doesn’t let her age slow her down — she’s been an exercise instructor for the past 15 years.

She also knows you’re never too old to keep up with technology. KARE-TV reports Taggert orders new books on Amazon and connects with family and friends on Facebook.

Jana Kyser, the property manager at the senior apartment complex where Taggert lives, says there’s one more piece of wisdom she’s learned from Taggert: “Honey, don’t ever let your hair go gray.”
