I am genuinely going to be bummed when Kalis starts slowing down. Lets hope not for a minute!
I was thinking about posting this clip but starting threads in here is potential for suicide...on to your comment, I'm also going to get really bummed and when I watched the video I thought, "How does this guy keep it going for so long and not get injured or burnt out?"
I know he's not jumping down stairs, but isn't he 36-38ish? Lots of pros fade by then. Your knees and ankles give out. His skating is still on point. Great clip!
