Just in case you have only heard the "Yeeeeagh" sound bites on the news, you may have missed that Howard Dean gave a little speech before it.
"If you would have told us a year ago we would come in third in Iowa, we would have taken anything for that...Not only are we going to New Hampshire ... we're going to South Carolina and Oklahoma and Arizona and North Dakota and New Mexico, and we're going to California and Texas and New York! And we're going to South Dakota and Oregon and Washington and Michigan. And then we're going to Washington, D.C. to take back the White House, Yeeeeeaaaaaah!"
Actually a very good speech considering that everyone in the room felt like they were kicked straight in the stones.
Now that we have that out of the way, dozens of enterprising people have remixed portions of the Dean speech into some hilarious songs.
I have found it helpful to do the stretching exercises my physical therapist recommends. Do some core strengthening exercises, such as the ones highlighted at The Mayo Clinic. By keeping your core strong, your back won't put itself in a position to cause that sciatica pain you are having.
