Happiness is...

 being able to breath freely through both nostrils at all hours...

Seriously, we take that for granted until we can't and you're waking up at night to drain, and sit upright, and the back of your throat and mouth go dry from having to mouth breathe because two of your vital passageways are so plugged up they are of no use, and you start to thinking... what if the throat/mouth closes? even if there's no danger of that...

Anways, grateful for free breathing here today, finally.  I hope it lasts. So much easier in life when you can just up and go and not think about taxing yourself.
