Observation of the day

When I lived in Ontario, I often suffered from migraines caused by the change in barometric pressure. I usually could tell if there was rain or wind on the way. My migraines were rarely, if ever, induced by food like so many of my fellow migraine sufferers. I find it interesting that since we've arrived in Costa Rica, I've not experienced one episode of headache trauma (for those who are blessed not to know what a migraine feels like, the use of the word 'trauma' is no exaggeration in my estimation). So, I'm not sure what the difference is as we certainly live through all kinds of barometric pressure change in the mountains. All I can say is that I'm ever glad that I've been spared so far.
