This is going to sound terribly, terribly wrong, but yes, size does matter. If it didn't, we wouldn't be so darn impressed with big things. But we are! I mean, why would countries all over the world try to build the tallest skyscrapers if not because of the allure and awe they inspire?
Part of that awe and allure is in how small big things can make humans feel. And part of it is surprise in how things we take for granted as being well-sized for us humans sometimes just aren't.
