Anyone seen that TV show? They certainly take some of the romance out of plastic surgery by showing, graphically, exactly what is being done to your body while you are under sedation. Ugh.
Someone I know who had implants told me that, regardless of which type you have, there is always a danger of them breaking or springing a leak. At the very least, a surgical repair would be required.
Participation in high risk sports can heighten that danger. She gave up skiing because she didn't want to risk additional surgery. Guess a skater would have to fall in a certain way..
