A hiding place where no one ever goes
Now... changing one thing. Backwards time travel isn't possible, so I'm fortunate to be an optimist. I look forward to future possibilities. I might as well be creative with this question. My answer: I'd change my parents and I'd get a better (university) education. If I could choose my parents, I'd select Herb Elliott and Grete Waitz. A 15-year age gap, but possible. I'd have been born in 1975. That'd make me 35 years of age. I'd be in the twilight of my professional running career — preparing to race the marathon at the XIX Commonwealth Games in Delhi. With parents like Herb and Grete I'd have been blessed with talent for running. I've always wondered what it's like to run with talent. How much easier is it?
The better education part of my answer is because it's something I really do miss. I was intelligent enough to go to university, but at the time, had my mind set on doing something that didn't require such an education. A well-rounded education, even if it seemingly serves no practical purpose (besides giving one a qualification and a high-paying career), provides knowledge of life and the world. There are things one just doesn't learn from the school of hard knocks.
