I have a barometer for a head.
Rapid changes in weather never bothered me as a teenager, but hitting my mid-twenties it started to. And the weather this winter has been absolutely bipolar--twenty and snowing one day, fifty and sunny the next. When the weather/atmospheric pressure shifts that rapidly it results in weird sinus pressure, like when you're driving up a mountain and that head pressure that builds up til your ears pop?
It kind of makes me feel like this.
