A ten-year-old boy who never should have waded out in Lake Michigan without knowing how to swim. Me. I can still remember the terror and helplessness of going under for the second time.
I'm alive today because someone on the shore saw me drowning. He jumped in and saved my life.
Then there were those 33 Chilean miners, trapped for 69 days in a collapsed mine a half mile down. Until that rescue capsule was lowered down that newly-created shaft. The rescuers brought every miner out alive.
