Concern about anesthesia for limb lengthening

Hello.

I am seriously considering undergoing a surgical procedure known as limb lengthening. It involves breaking my legs and inserting implants to straighten out my legs to even proportions. I was born with one leg slightly longer than the other, but with limb lengthening, it will correct that, furthermore, I will end up a few inches taller, which is icing on the cake. However, my main concern is not the operation itself, but the application of anesthesia. I've read tons of horror stories of patients dying from just simple outpatient surgical procedures that it is making me have second thoughts. I have a muscular body and I eat right, therefore, I am in tip-top shape that I could qualify for the Olympics! The dangers from this operation include death, fat embolism, heart attacked, chest infection, blood clot in legs.

1. What are my chances of dying from all the aforementioned things?

2. Should I worry more about anesthesia than the operation itself?

3. What are my chances of survival?

4. Would it be better if I had local anesthesia instead?
