In case anyone forgot, the world number one on the women's side of the professional golf world is Lydia Ko. And she's 17, which is awesome. (Don't think about what you were doing when you were 17 -- that'll just make us all start feeling bad.)
The most recent demonstration of her age happened at a tattoo parlor. It's tough to see if you're not looking closely, but on Ko's right wrist is a string of Roman Numerals.
We're not sure where she got it done, but it's pretty common to have to be over 18 to get a tattoo. Ko was 16 at the time, so she needed her parents' consent.
"My parents were there, and I felt like it was a very memorable win so I got that tatted up," she told Golfweek on Monday.
Ko isn't the only professional golfer who has a tattoo, but we're guessing she's one of the few needing her parents' permission to get it.
