A plaster on a face means...

A scene from a cartoon show a little kid with a plaster on his face. The character is some kind of heroic type. Thus, by drawing that plaster on his face should mean to suggest that he is rugged.

However, to me, I think otherwise ... . Drawing a cut on his face should suggest rugged, while a plaster suggests he requires care for little wounds.

Knowing the ideal and trying to do achieve it are good. However, ensuring the ideal at all instances may be unwise. After we, humans, learned about germs and bacteria, we know that what seems clean is actually not. Now, we know the ideal of clean is when even these invisible to naked eyes germs and bacteria aren't around.

Then, we behave in more hygienic ways. Keeping clean has quite a different meaning since then. So, we have been trying to achieve the state of clean.

Then, we invented ways to kill all these. By pasting plaster over little cuts so that any germs there can be killed by the chemicals, we achieve the ideal at the wound. That, I think is somehow over doing it.

I think that behind all the sciences is the acknowledgment that all existences are results from design. I trust our designer much more than human inventors and inventions.
