Barometric Pressure

When I get a headache it seems to correlate with severe drops in barometric pressure. Obviously barometric pressure is not something I can control but I feel better about taking headache medicine after I have seen the evidence of a pressure drop on the weather graph.

Our local dairy farmer told me that his pregnant cows tend to calve during a high pressure system. I want to see a cow give birth! I am watching for weather indicators intercepting our need for milk.
