I think it's a good nudge tbh. Stairs are proven again and again to be an incredibly healthy workout given that you don't have issues with your knees.
I just came back from Japan and 20k steps a day and hundreds of stairs for a month really put me in shape and made me realize how important good shoes are lol
This would encourage me to choose physical fitness, or to laugh as my tired ass goes up the escalator. I certainly see where there is room for hurt feelings (especially with regards to health issues), but this is pretty effective given that it is in a different language and I instantly understood it.
Korean are savage, you will meet someone you haven't seen in a while,and they will look at you straight in the eyes znd tell you " Wow, you gained weight!!!" Just after saying "hi!"
That doesn't look like Korea, I'm guessing Japan. The text looks like Chinese characters, and Korea hasn't used those for hundreds of years. Korean script is more blocky and easily recognizable even with this incredible level of blur.
