I find that if we don't punctuate our sentences it seems like we're talking really quickly that there's no time to add full stops and commas and etc so it's as if we're out of breath or we just don't want any ideas to slip by into forgottenness hence we blurt everything out as fast as our mouths allow us and also another thing about not punctuating our supposed to be sentences is that I tend to read the text faster for some reason oh wait obviously since there are no commas or periods to tell our brains when to stop.

And.I.find.that.if.i.conveniently.place.fullstops.after.every.word.it's.as.if.I'm.talking.terribly.slowly.And.i.bet.you.are.reading.this.block.of.text.really.really.really.really.really.
really.really.slowly.too.because.the.periods.prompt.our.brain.to.pause.which.is.the.
purpose.of.fullstops.anyway.
