Inspiration or insanity?

I met a guy at the Burgos bus station this morning. 38 year old man on his six week vacation from a town job painting public buildings outside of Barcelona, doing the Camino for the third time. Friendly and warm with super clear blue eyes and a relentlessly positive spirit. I saw his foot was heavily bandaged and asked him about it. He had walked from Roncesvalles to Burgos in 7 days, more than 25 miles a day, quite a feat. But then he took a fall and seriously hurt his ankle (couldn't understand exactly, something about a tendon?) and was taken by ambulance to a hospital in Burgos where he spent two nights, then last night in an albergue. And now he was going back to the place he stopped to continue walking!!!!!!!!!! He said it's all mental, that he will overcome the pain. I think he's nuts, he could do serious damage, but yikes what an attitude. I'm humbled. No, I would never do such a thing--he could permanently do himself in--but I will keep him in mind when I feel sorry for myself dealing with a little foot pain.
