There's a weird addendum to my melanoma story. My wife was working at the time at the Hospice Thrift store in Hilton Head. One day she noticed a gentleman in the shop who spent all his time staring at her leg - every time she looked up, there he was wordlessly staring at the same spot on her leg. Seemed like a signal that there might be something there to be looked at - and there was: melanoma, caught very early and excised without complication. We never found out who the silent observer was, but we are grateful to him.
