Why, thank you?

Strangest compliment ever came from a friend yesterday whilst talking about some spy that got shot down from a plane and survived the fall. She just looks at me and says "I think you would be the kind of person that would survive a 70,000 ft fall..." When I received this with a puzzled expression (indeed exclamation) she said "That's a compliment, I wouldn't last 5 ft."

I don't know what is more bewildering. The idea that there is a type of person that could survive that, the suggestion that I seem to be of such set or that she envisages herself as someone that having fallen 5 feet through the air would instantaneously perish?!?
