The Doctor was looking at him, his heart rate had increased. He breathed deeply trying to calm himself, He knew it wasn't good for his hearts to beat that fast after he had nearly died . He looked at Death "Yeah I know... Just cant help it sometimes."
Jack was looking at the Doctor "Yeah Death is right, we don't want you having a heart attack." He was thinking "Finding the leader be wise."
"I won;t have a heart attack, I may be old, But my body isn't and I don't suffer from old age stuff, Just little stressed and nervous."
