You're describing my dad perfectly. He worked as much as I do (plus he was doing hard physical labor...) until he died of cancer in 2009. He's the reason I dedicated myself to work as much as I could as early as I could, so I could get myself to a point of financial independence. He never got to enjoy his retirement because he sacrificed his life to adopt me, so I feel a sense of urgency to enjoy life as much as I can in his honor.
