Comments left by Kentaro Miura (author of Berserk) on Young Animal Magazine when he was drawing Berserk and commentaries at the end of the book.
This has been shared before but it is well known that manga authors have brutal schedules they have to work under. So many have died before old age due to health issues.
To quote Junji Ito:
โSleep is very important. Everyone get enough sleep. Many manga artists die young and itโs because they donโt sleep. Your best ideas will come to you when youโre sleeping. Please everyone get some sleep.โ
Remember Manga authors are human beings that deserve better work conditions in their industry.
