You know you're too involved in karate when:
sis: hurry up and get dressed!
me: what the hell did I just say?
on a side note, I got my heart palpitation in karate for like the fourth of fifth time. Even though I took permission to sit aside whenever I get it, I can't bring myself to just suddenly leave the class. It's a little awkward. That cost me an extra minute of accelerated heart beatings.
