And my knees are still burning as I write this post.

Today I learned that even though I ran and played soccer for years through middle and high schools, I am now terrible at running.

This was determined after I had a random urge to go running, then wiped out on the sidewalk within about a minute, didn't realize my knees were bleeding like crazy until about 7 minutes later, then had to go to the bathroom in the league to clean up all of the blood.  On top of that, after this all happened, I could only run for about 10 more minutes because I was so exhausted from being so out of shape.  

I'm thinking it will be another few years until I get that urge again.
