Rock Band 2

I totally played Rock Band 2 all night, when I really should have been working on my entry for National Boards, which I video taped today.  But I do feel that I got a little exercise while playing, because I made myself get up and dance around while I sang.  I even  ran out of breath during a couple of songs. Rock Band really isn't healty for my voice, since a majority of the songs are lower than my vocal range, yet I still belt them out through my chest.  

I think all of my posts are going to end with a question, because I really like getting comments.  So, what should you be doing right now, instead of playing on the internet?
