So my 14mm abdominal aorta is not more likely to rupture than a normal aorta? it's actually less likely due to laplace law? can i weight lift much?

CameToThRightLaPlace: Not "due" to Laplace's Law. LaPlace's Law came about by the Laws of Nature. But like I said, I wouldn't worry too much about it. Lift away, just be smart about it. Proper posture and breathing. Even Arnold had to learn that the hard way! But I sense you need more info or reassurance so do some research on the web or see a cardiologist or internist. Or talk to the guy who ordered the CT.
