Angelina i think when parents ask their daughter to wear a cb, they must always be reachable.
I think there has to be a way to get the key when they are not reachable for emergencies but it is not really necessary that it has to be extremely fast and always.
I think in a real situation of emergency the belt could be easily destroyed by the hospital staff or something like that.
I was never in a situation where it was necessary that I get out of the belt for emergency reason. When I am at work it is not possible, if I am at Daniel's place it is not possible and so on. If I go on holiday with Daniel it won't be possible for weeks.
