Besides the fact that data (which I have cited and you have not) beats any anecdote, your analogy is awful. For one thing, since I happen to know people in the tree business, I can assure you that the pros use equipment the amateur isn't likely to have. It's a different activity. Second, people are broadly similar when it comes to how their bodies will handle tree planting. There's no huge difference in speed and resulting stresses on the body. What's likely to injure one person is likely to injure another, even if one is twenty and fit while the other is fifty and overweight. By contrast, few runners will ever be operating in the same milieu as someone who's competitive at the college level. Most have never been capable of it, and almost none once they've passed forty. Injury risks are most definitely not comparable across the two groups. You're an outlier. You should be proud of that, and clearly are, but you want to have your cake too. You want to believe, contrary to the evidence I've cited, that your outlier's experience is relevant for people who have never had the benefit of working with professional coaches and trainers, for whom any likelihood of that is decades behind them, who might have struggled with all sorts of mid-life health issues before they took up running. That's the typical beginning runner who needs to know this stuff. They're ill served by your willingness to hold forth without benefit of relevant experience or familiarity with the actual science of the matter. Was there ever any rational expectation that your anecdote - which is the only thing you offered, in contrast to what you were supposedly answering - would help anyone else avoid injury? If not, then why did you feel the need to speak up?
