Learn from the young!!
I was terrified of my upcoming fusion (one level), but not now.
I got a boost, that knocked the fear out of me. But a terrible way to get over the fear.
My 17 yr old niece up North was in a car accident and it was totalled, she almost died. It is so bad, she now has screws, rods and pins in both legs and arms, neck and her back. She said she is a walking toolbox. (plus she still has her sense of humor)
If she can do this at 17 (not like she had a choice, then I can too).
