Uncommon Disease

I have a friend. He recently recovered from a lung surgery. He was operated because of a disease called Pneumothorax. Say what? Pneumothorax. From wiki...

In medicine (pulmonology), a pneumothorax, or collapsed lung, is a potential medical emergency caused by accumulation of air or gas in the pleural cavity, occurring as a result of disease or injury.

This friend of mine said that it is common among tall and thin male, whose age is 20~40. From wiki again...

Spontaneous pneumothoraces are reported in young people with a tall stature. As men are generally taller than women, there is a preponderance among males. The reason for this association, while unknown, is hypothesized to be the presence of subtle abnormalities in connective tissue.

It is cool for me to learn something new especially when it comes to the human body. Even so, I never thought of becoming a doctor. Simply, its God's sovereignty that fascinates me. End.
