Don’t get me wrong buddy, I completely respect the job he does, the hours and the care he put into his work and the way he gives importance and priority to progression of the manga despite his health conditions. I, myself, sleep 3-4 hours maximum everyday due to my work (RFIC Design Engineer) and spend my entire weeks/months for designing and simulating and sending multiple circuits to production (not mentioning test and redesign steps lol) simultaneously without making any single mistake and satisfying design requirements. Considering that I have started to have this kind of lifestyle for the last 4 years, I can only imagine how tiring it must be for a man with health condition to do it for 20 years.
It is just that, I get carried away sometimes and might become a bit too perfectionist. As a design engineer and an academician, I sometimes lean towards no-break, only-work and militaristic kind of lifestyle. If anything, it was me getting carried away at the moment and I apologize sincerely. :)
