Man if i was 20 feet tall o would run things, Maybe.I am allready taller than most of my family or friends,but if I was 20 feet tall. I would be abel to play and beat anyone at basket ball or foot ball even if i do not realy like sports. If you think about it i would not be abel to do a-lot of the things i like to do. I would not be abel to sleep in my bed becasue i would not be abel to fit in it. I would not be abel to go inside my house with ease since the door is smaller than 20 feet. I would not be abel to go out with anyone be casue lets face it, who would want to go out with a gigant. Know that i9 think about it being extremly big would kind of suck... big time.
