@lajbel I mean... In general, society seems to have agreed that topics such as 'personal hygiene', 'personal finances & budgeting', 'cleaning the house', 'urban navigation', 'debating', 'archival', 'gardening', 'chess', 'rudimentary human medicine' and others are not part of the school curriculum. You learn (and refine) them from your family/legal guardians or on your own.
And today it has become easier than ever to get information on any given topic: If (just as an example) 'I' wanted to know how to take care of my body in a region where I received a piercing or tattoo and didn't pay attention to the person who did it (or received poor guidance), there is _an embarrassment_of_riches_ in the form of written guides and videos which explain the 'ins and outs'. Everyone you meet on Newgrounds has access to the internet in some capacity. If you want to know something 'that humans know', you can look it up - as long as it isn't a classified secret.

@Yatsufusa Thanks for info. Will share with anyone who needs. I in general say this should be informed by health/medics in general, but they are worried about making you guilty
