Every once in a while you come across an inspirational story about a seemingly average human being who achieves great things, and it makes you really question what you're doing with your life. The story of Mieko Nagaoka, the woman who became the first 100-year-old to complete a 1,500-meter freestyle swim, is just that type of story.

There may not have been much competition in her age group, as she was the only participant, but the fact that she was the world's first 100-year-old to ever complete the feat demonstrates her superb determination. She finished the 1,500 meters in 1 hour and 15 minutes using a backstroke. Nagaoka now holds 24 short- and long- distance swim records in her age group.

“She is some woman,” her son, Hiroki, told CNN. “The word 'first' means no one has done it. It was awesome that my mother has challenged and accomplished her goal at her age. She still uses her brain and tries to figure out the best way to swim; she still even tries to change her swimming form to challenge for a record. I’m really proud of her.”

Nagaoka is particularly inspiring because she didn't even begin swimming until she was 82 as a form of physical therapy for troublesome knees. She began to train several times a week. She now swims two hours at a time, four days a week. She says, “I want to swim until I turn 105, if I can live that long.”

What an inspiration!
