Wendy Bonython: So we've recently seen a very large scale product recall in Australia in the Takata airbags. Everybody knows what make and model motorcar they have, everybody who's been caught up with that has been contacted on numerous occasions to get that airbag replaced. If we can do it with an airbag in cars, why can't we do it with devices like pacemakers, implanted joints, things like that, that are far more directly involved in personal safety?
