I have wondered if she can scuba dive and if so how far down ? Most cameras I sell will rupture at 16 feet I wonder if she could hit 20 feet or would they like yeah let's not speak of the night mare that would happen ugh me and my horrid thoughts 
she should have no problem scuba diving, as water can not be compressed- i.e. reason why hydraulics work. Only concern she would have is if their was air pockets in her breast, and then that would be more fear of climbing mt. everest due to LESS AIR PRESSURE and expansion causing rupture, going deeper with scuba diving is more pressure and thus would just cause the air pocket to shrink.
