NCT’s Mark has always been known as one of the busiest idols in the industry, relentlessly debuting in multiple groups such as NCT 127, NCT Dream, SuperM, as a soloist and more. While fans are proud of his achievements, his latest health checkup results have fans more worried than ever.
During a recent evaluation, Mark underwent a body composition and vitality test, and the results stunned viewers. According to the exam, Mark’s body activity and biological age measured on the same level as people in their 30s to 40s, despite the idol still being in his mid-twenties. The revelation sent shockwaves across online communities, where fans expressed disbelief that Mark’s physical condition had aged so dramatically.

What worried fans even more was the medical explanation that followed.
For Mark, it’s at the level of people in their 30s and 40s. The body activity level and the body aging level, it’s saying that you’re aging quickly. You can’t feel them because you’re young now, but you’ll feel it once you’re past your 30s. Things like not being able to digest well. It’s important that you’re aware of it now.
The doctor noted that Mark may not feel the effects right now because he is still young and physically resilient, but once he reaches his thirties, the accumulated strain from years of nonstop schedules, touring, rehearsals, and overlapping group activities, may begin to manifest much more clearly. The idea that his current state is a silent warning sign left many feeling anxious and protective.
Idols are overworked, sleep deprived, they don't eat that much and heavily rely on IV drips and tons of supplements most of the time to function. It's so normalized in kpop…. it's sickening. They look good on the outside but they are not ok inside. https://t.co/814PSeP2y9

Being an idol is an extreme job that is not for the weak. Mark’s long history of overwork without extended rest, causes the toll that such a demanding lifestyle inevitably takes on the body.
thinking about the life these idols live, the extreme dieting, not getting enough nutrients, being barely 60kg as a grown man, the overworking, barely getting any sleep, the stress they go through, you realise none of these idols will be seeing their 70's https://t.co/V6OPr88Xh8

NCTzens are hoping this moment becomes a wake-up call for the company to prioritize his health.
