Every three years I go in for my annual checkup. I passed all physical exams and my blood pressure was in a good place. Blood work will be back in a few days at which time I will get the verdict on cholesterol and triglycerides which are always out of whack. I got a prescription for Diomox (for high-altitude climbing) and vaccinations for Typhoid and Hepatitis A for my trip to Nepal later this year. I was covered in Band-Aids as I left the office and hungry as hell having skipped breakfast as required for accurate blood work. As I get older I might consider having my annual checkup every two years.
