Can you play football with a CI? Can you play Hockey? Can you play Basketball w/o worrying that a ball can bean right square on the CI? Baseball for the same reason? How about wrestling? Vollyball (again about the ball vs CI) And yes you're right about scuba diving, too bad, too sad. A missed opportunity.
These are popular sports and none will be able to play with CI.
That's why I advocate the rights of a child to choose whether or not he/she wants a CI. If a child finds out there's certain sports that he/she can't play because of CI and really wants to play it, yet has no say because a parent felt that he/she needs to "fix" their child, thereby denying the child a dream of playing a sport that he/she wants to play.
When the child reaches the age of 18, that's when he/she can decide for themselves if they want that implant, along with a well informed decision of the pros and cons associated with having a CI. Plus being informed of the dangers of contracting meningitis which can have the potentiality of killing the implanted user, no matter how well medicated they are weeks to months prior to surgery, the risk is still there.
Personally, I can't understand why any human being sees a child who without a CI is perfectly capable of doing anything they want, except hear, be considered "defective" in any way, shape and form.
There's nothing wrong with being deaf.
What's wrong is the misconceptions, false fears, falsely informed that a child cannot have a happy and productive life if she/he is deaf.
