Hello Blog,  I'm taking a deep breath.  Come to find out, sighing is very healthy and gives you extra oxygen.  Try it.  I also understand that when we are stressed, we take short shallow breaths without even realizing it.  So pause and take some deep breaths.  I've been sleep deprived lately.  Last year when I was running regularly, my sleeping was much better.  School,  traveling to family, grand babies, all good things, company, more school coming up...all good things.  I need more sleep!!!!!!!!!!!!!!!
