This anime really hits me for some reason, we should try our best to make the cells that are working at our body have a nice work environment, yes they might be only cells but still, what will you do if your a cell living in such poor lifestyle like smoking, drinking, and sleep deprivation? of course you'll hate the workplace and wont like to work anymore. therefore we should maintain a healthy lifestyle such as sleeping for 8 hrs etc.. thats why im giving this anime a overall 10 score as it helps us humans to take care of our body seriously and tells us theoutcome if we didnt.
