So I have gone back to look up the paragraph from his blog:
I'm 100-percent healed from my big injury that sidelined us during such an exciting season last year. Feeling like my old self again made me conscious of the fact that my body may have been compensating long before pain let me know that something was wrong. It feels so good to be on the other side of that hurdle, but I am more aware now of my own mortality as an athlete. None of us are guaranteed a certain amount of "sport life." It was never in my nature to be a nervous competitor, but this year should be extra enjoyable just to have the gift of training and competition back once again.
