No but aortic stenosis can be a real bitch as you get older. The distinguishing feature of Marfan's syndrome (which Lincoln might have suffered from) is that your wing span is as long as your height or when your arms are at your sides your finger tips can touch your knees.
You sure about this, my wingspan is significantly longer than my height and I am normal.
I believe Mar fan's is usually seen on people average height or taller than average and gives them very long limbs, this little kid looks to have a normal kid wingspan just on a very short torso. Hope nothings wrong with his internal organs.
