Opossums can grunt like pigs. I thought I had a pig living in my yard, because I heard grunts and squeaks (babies) passing by under my window one summer morning. Got a trailcam and it's a possum.
If you collect knives you will cut yourself more often, even if you are good at handling knives. The big-picture reason "more knives, more cuts" makes sense. But how does that work out in the little picture? This is due to specific reasons you probably don't anticipate until you have some hindsight.
If you can imagine it, you can probably build it, do it, design it, or construct it somehow. I never realized how pessimistic I was about this concept until someone said "it doesn't have to be this way" and it was like a huge lightbulb went off and I sat there with my mouth hanging open. Basically, nothing has to be that way. Some things will _probably_ be a certain way. But confusing those two principles propagates lots of really unfortunate stuff in our world, because we think "reality" is formed by the latter, and basically give up or don't try anything new.
Eating hard breath mints can break your teeth. Huh? And also: Duh!
Spinach is healthy. It can also send you to the ER with oxalate issues like kidney stones. You can be a skinny green-diet superstar and spinach, almonds, etc. will absolutely stab you in the back.
You can lose tons of weight while eating boxes of candy bars. People will warn you not to do that, but there are easy workarounds for all of their concerns.
Pickle juice can hydrate you. But it can also destroy you in one of the most comical ways possible.
That's all I got for now
