Probably. If you think about it, shooting movies, videos, doing promotions, meet and greets, rehearsals, tours, etc would mean a very hectic schedule and working long nights. Even people working the usual graveyard shift would often get sick. And there's probably a lot of pressure that comes with show biz.
Is it really that hard become actor/idol/star? My bias always go to hospital (once/twice)if shooting his drama.. (sudenly loving him more)
