Some ppl ( one out of like 1000 ) will grow enormous out of everything.. like 2m 30cm even when their parents are smaller than the average. Heard they have difficulty breathing and are more likely to develop cardinal disease due to a lot of burden on their hearts. But is it a disease? Some kinda abnormal genes?
It is a genetic disorder, called Marfan's Sydrome. Abraham Lincoln is thought to have it. It causes stress on heart, because it has to work extra hard to pump blood to all organs in the body because they are so stretched out.
