Obstacles are plentiful in outdoor activities: long switchbacks, brutal portages, downed trees across the trail.
Those obstacles can be avoided. But one can't: the passage of time. It changes the dynamic with mainstays like backpacking, canoeing and mountain biking. Sometimes the gradual effects of age, of wear and tear on the body, of injuries or even disease become factors in an outdoors lifestyle.
And yet, a group of Minnesotans, middle-aged and older, queried about their activities had a common reaction to the impact of age. They make accommodations as they add years, but they are not taking to rocking chairs. (See more related comments here.)
Some national statistics show they're outliers by just moving their bodies.
A 2016 study by the Centers for Disease Control and Prevention found that more than one in four U.S. adults older than 50 are inactive — and that inactivity increased with age.
"I'm not going to stop," said Karen Neal, 73. She is a 47-year resident of Grand Marais and a veteran backpacker, hiker and canoeist. "If I stop, I die. That's how I see it."
Neal has had to make adjustments. "I certainly have slowed down," she said. "I had a torn meniscus in my knee when I was 71, and my doctor said it would never be the same. I was hoping he was wrong, but he wasn't."
That means shortening backpack trips and looking for ways to make trip chores easier. "I use a straw water filter now," Neal said. "Going down to the lake and squatting for a half-hour with a [pump] filter is harder to do when you're 70. I do it the easiest way possible now."
