Thanks everyone. It's my mother's boyfriend, well ex-boyfriend but they're still friends.

He has small cell cancer, not sure what kind. He is going for his final round of chemo then he told us "it's all downhill from there" but he is planning a deep sea fishing trip with his buddies in the next few weeks and still gets out and lives his life or what he has left of it, one thing is for sure he is very brave and I am amazed at his courage and attitude. Thanks for the advice everyone!
