My daughter is studying to be a medical doctor and she is pretty active in the univ aikido club. I heard from other parent that one of the instructors is very vicious and has injured quite a number of students where he instructs. Among the injuries I was told were dislocated shoulder, broken collar bone and torn ligaments to the elbows and wrists. I am more concerned with ligament injuries as I was informed that such injuries do not heal 100% and pains and other ails will come back to haunt from time to time. I am worried that such injury will impede my daughter's ambition of being a surgeon.
