At either end of the spectrum of life, people are doing amazing things.

A child just days away from her third birthday is setting archery marks in India. Earlier this month, a 95-year-old man set a world record in a 200-meter indoor race.

Take that, slackers.

The latest example of who are doing far more amazing things than you are every single day before you’ve even had breakfast comes from Japan, where Mieko Nagaoka became the first 100-year-old to complete a 1,500-meter freestyle swim in a 25-meter pool Saturday. Granted, there isn’t a lot of competition in her 100-104 age group — she was the only entrant Saturday — but her feat was nonetheless impressive. Nagaoka finished in a time of just over 1 hour and 15 minutes, using a backstroke the whole way, the BBC reports. It was just the latest record for the woman who holds 24 age-group records over short and long distances.

And, if there are two takeaway sfron Nagaoka’s dedication, it’s that it’s never too late to get moving and never stop. She began swimming when she was 82 as therapy for her knees, then began training several times a week.

“She is some woman,” her son, Hiroki, told CNN. “The world 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, a native of Yamaguchi, trains two hours at a time, four days a week.

“I want to swim until I turn 105,” she told Japan’s Kyodo news agency, “if I can live that long.”
