RUTheJollyGreenGiant: No, actually it's the other way around. The bigger it gets the less pressure is necessary to stretch it further. It's called the Law of LaPlace (the guy who figured it out-he reduced it to a mathematical formula).It's a bit more complicated than that, having to do with tissue elasticity, your size, etc.As for your aorta,don't worry too much, as long as you are otherwise healthy and not 8 ft tall.
