Breast implants are not permanent..even if your experience is good to start.
They have to be replaced..at some point...when this happens ...there is a possibility that it may not go as well as the last surgery. And then you can have surgery and it may not go as well..on and on...so it is not a one time investment ..or even twice...it could rule or ruin you financially.
As for the quality of life..it changes..if you are an active woman ..you will find that everything physical is and issue..water skiing , jogging, snowboarding..having sex..
At what point do you think you will stop having breast surgeries..40, 60 80..??
Very few pros...Tons of cons...
