I can't imagine not feeling sore! I am the opposite from you, and my need to pay attention to rest, recovery, and stretching is increasing exponentially, as I age. I can feel sore from taking a 2 mile walk, despite all of the the stuff I do. I hate this.
Something makes me think that a lot of really good athletes don't feel pain and soreness until it's really bad. My son who raced was like this, and I think it has a lot to so with the ability to endure a high level of suffering.
