Random Concepts

So basically these concepts don't fall under any special category .

also disclaimer: some of these ive researched myself and others come from youtube & my bestfriend( who happens to be one of the designers of this website so shout out to her) >.<

hearts: so like i find it weird that we know hearts to be <3 you know... but hearts don't effin look nothing like that sooooo wth. whats up with that ? like where did we get this symbol from ?

Okay so these two not sure if they're concepts but....

SO if you hit your self really hard and it hurts does that make you weak or strong? like this one makes my brain hurt, my best friend told me this one and it's been in my brain forever.

humans need air to live but they can't see it right? so can fish see water ?
