You know what I've realized? There's a very basic thing that I've taken for granted for most of my life - the ability to breath.
The ability to take a nice deep breath any time I like is something I miss. Not just when I have a sinus infection, though that makes it much worse.
It's not the altitude, it's the allergies.
I go back to the acupuncturist on the 17th. Let's hope it works.
