I sincerely agree with what you said. you've got very satisfactory reasons. other than them arsimed water lifting pressure. Newton's floor-breaking assembly. these are all random things. humans usually have different things in their lives. maybe even now an invention stands inside the way. we just do not see it. folks that give an explanation for what those differences are are known as inventors. This issue is immortal to the factor. for us to sign a treaty altogether. simply to be extra cautious. we want to note the differences in our surroundings. @sean-king
