Sorry, I sold the '47 Willys Army Jeep a year or so ago. It was very much a "you really like power steering where the power doesn't come from your shoulders?" thing, these new Mules/Whatevers are so much nicer to drive. They'll spoil you.
Now about 50, I don't worry so much about my mortality anymore because I spend all my time thinking about my morbidity. Fatter, slower, forgetful, tired, creaky joints, recurring pains, random pains, stiffness, lower alcohol tolerance, lower coffee tolerance, lower libido, higher cholesterol and related dietary restrictions, more invasive routine medical exams. I can't worry about what's going to happen in the future because I'm busy lamenting what is happening to me right now. And, I'm considered to be in good health.
Pancreatic cancer. I'm not sure there's a ton to do except to try to eat right, exercise and keep getting checked.
