It was early Sunday morning and the kids were still asleep as I finished my 10 k run. As I was admiring the view from the ski-hill I had just sprinted up it, occurred to me I never hear any parents talk about my most valued asset as a parent. The one that makes parenting so much less stressful, intense, and demanding. The one I can’t live without for a single day. Extreme fitness, a parental gold mine.
