I've got old injuries from martial arts, but they don't show up much if I'm not doing any high kicks while jumping, etc. They're the main reason I don't do martial arts exams any more, because the program requires to do some things that open up old injuries and then my leg hurts for the next six months.
I'm ill usually once a year for a few days, when winter sets in.
I've got a health insurance given by my employer, but I haven't used it in two years I've had it.
I had my last overall medical check up in the second grade at school. All sportsmen are required to do it once a year, but I just go to my doctor and ask her to give me that paper with no medical procedures, but she usually insists on at least hearing my heart beat.
