Get up from your computer.  Really.  This blog is less important than your physical well-being.

Get up...take a deep breath in, stretch your hands to the sky, slowly bringing your hands down and breath out.  Breathe in again and stretch slowly to the floor.  Breathe out as your come back to standing.  Repeat 3 times. 

Remember, your brain will only last as long as your body.  Take care of it and stretch Now!
