Personalized Advertisement in Korea

We received an advertisement from the GS supermarket in seoul. I agree that that wold normally not warrant a blogpost, however this was quite special in the way that it was personalized. This advertisement contained 10% discount coupons for the items we most frequently brought at GS. In the order of frequency, so ham was on place one, followed by milk, eggs, laundry detergent, chicken meat, cornflakes, cheese, butter and kim. 

I didn't really decide yet if i like that (are they also saving which brand of condoms we prefer? when do they delete these data? do i want my landlord to know what we buy?), but I'm quite fascinated. The woes and wonders of modern technology....

Playground in Yoido / Hangang Park

My parents came to Korea, so we went to the Hangang and Yoido park. There we found a playground with the.... Ummm 'things' ? below.
I never saw playground equipment like that.

This is medium entertaining, you are supposed to step onto the boards, hold tight and been turned by a friend.

The concept of this slide  is quite nice. You step onto the small platform which is able to slide along the rail, and then propel your self around by holding onto the chains above.
Sounds nice in theory but it's not sliding well enough and it's also nearly impossible to get high on the sides.

This is Tarzan rail slide. Similar ones I saw previously in Germany, but normally longer and straight, not curved. This is actually fun but because you have to hang on to the handle it's hard on the arms.
