Almost every time I run, I am surprised by my age (54). I feel great doing so and love it as much as I did when I first started at 10. Most of my surprise comes from the example of my father. While he was a great role model for me, in the running department, I only saw him engage in the activity exactly one time and that lasted for about 5 seconds max.
Growing up, I always thought I'd be like him and, as far as running goes, I'm glad to find this not to be the case.
What else surprises me about my age? How happy I am, how easy it is to stay fit, how much my kids have followed me and my wife down the fitness path without us ever having to talk them into it. They just embraced the lifestyle.
Last thing, a couple of years ago, I had a spin through the cancer world. My doctors kept telling me they never see someone like me (ie height/weight appropriate, strong heart etc). I don't have a personal physician, don't take any medication and take every medical evaluation with a very skeptical eye. My doctors cured me of cancer but, oh my God, were they inconsistent, wrong and ill informed in a holistic sense throughout much of the journey.
This has been on my mind in the pandemic. So many people say, "Trust the science." While I have enough of an education to understand what they're getting at, I have enough personal experience to know that science is hugely fallible, medicine is a business and a doctor's first inclination is to make the most cautious recommendation available. If you're a runner, in good health with few "conditions," chances are you know your body much better than any doctor. Trust that you know what risks you should be taking and how you should live your life. Don't leave it in the hands of someone just because they have a medical degree. Respect science but don't abdicate authority over your health, hold on to that with every ounce of strength you have.
