"It depends on the damage," she says. "I lost my hand in a flying accident a few years ago, and it didn't leak fluids and I could still use the rest of my arm. My husband's friend put it back on for me, and it's as good as new."

She holds up her left arm. No trace of any damage there.

"But if I'm too badly injured, I am told, the energy of my construction and functioning will be released all at once."

Explosively.
