Wednesday weekly publication broadcast on his YouTube Channel.

This week Kim Hyun Joong decided to follow-up with a second test to check his level of adultism (Kkondae test).

Here is a definition among many others to understand what adultism is:
« Behavior and attitudes that are based on the principal that adults are better than young people and that they are authorized, as a result, to behave towards them in any way, without asking their opinion.

To sum up, it a combination of privileges and tolerances granted to adults based on the fact that they are older and/or have more experience.
Tolerance that is denied to young people because they are young (examples: choice of meals, time in the shower, choice of clothing, establishment of rules…)

Why does he take this test, one may wonder?

To understand his attitude and reactions vis-à-vis the teams he manages as the leader of the Gemini band and head of the Henecia company.
