I'll have elective plastic surgery the day that surgeons stop saying "Well, you know, all surgeries have some risk."
I'd just never risk a general anethestic and the risk of infection for the sake of better arms, or boobs or whatever.
I do understand what you're saying, but ...
To me that's like saying "well, I'll get in a car and drive the day that the auto industry says there's no chance my car will ever crash".
Life is inherently risky. You put your life at risk every time you step in the bathtub. Every time you get in a car. Every time you walk across the street. Every time you eat food that wasn't grown by your own hand (and even then you could choke to death on your own home grown grape tomato!).
If you get all the information available, properly assess your risk factors, and make an informed decision, surgery can be no more or less risky than any of the things you do daily.
There are no guarantees in life. Be smart, be careful, make informed decisions ... and then enjoy the rest!
And yes, I plan to have at the very least a tummy tuck after I'm doing losing all my weight. 103-ish lbs and I know I"ll need it.
