I broken my toe once and pulled muscle and sprainded tendon several times but I've never broken my collabone or torn ligament. I sometimes have a cold and a cough but I've never had anything more serious, like meningitis or hepatitis. I never have problems sleeping but I do occasionally feel irritable and stressed out. To keep healthy, I do spot and sleep at least 6-7 hours a day. In my opinion, the most dangerous diseases in my country are cencer and strokes because of the environment.
