How do you imagine a 105-year-old spending her birthday?

Teaching a yoga class is probably the last thing that comes to mind, but not for Lil Hansen of Ludington, Michigan.

The centenarian tuned 105 in late November and celebrated her human holiday by doing what she normally does — heading down to the local senior center to lead a yoga class for those in their 70’s and 80’s.

“I don’t feel any different,” she told WZZM13. “I’m just a little more careful than I was years ago, but I don’t feel old. I don’t think about it. I just keep going.”

Hansen is the President of her Bridge club, and as you can see in these videos, she’s as spry as those she teaches.
