Had to laugh at your comment.."bullet proof".... I went to lunch with a real good friend ( from our early AF wives days) a few years ago. She asked, "Did you ever think we'd live this long?" I think we figured anyone over 40 was ancient back then....
Reminded me of the t-shirt that reads, "If I'd Have Known I Was Going to Live This Long, I'd Have Taken Better Care of Myself!"
