Bad guys beware — a butt-kicking grandmother has her eyes on you.

Iris Davis isn’t your average 62 year old. At 5 feet, 1 inch and weighing 100 pounds she’s a champion bodybuilder. And when she saw an armed robber running from the cops, she sprung into action.

But that isn’t the toughest battle she ever faced. At age 45, she was diagnosed with a virus that attacks the brain, and it left her paralyzed for five months.

She explained to Growing Bolder how she overcame the illness and what her journey from sickness to vitality has taught her about life and growing older.
