Dragonfly migratory rule

Weight less than a paper clip, dragonflies can't fly against the wind. How do they migrate? An other informative program from KERA, Fresh Air told the story.

Dragonflies would move on successive cold nights, for example yesterday night's low was 50 degrees and tonight's low is at 40 degree. They will migration with the wind. The reason is that usually successive cold weather is an indication of a cold front moving in and the wind would move move the cold front, therefore as these tiny insects move with the tail wind, they are migrating to to a warmer weather.

I, as a human being, always put too much reasonings into my decisions. Especially I was trained to be analytical. When I was introduced to technical analysis of stock chart, I though I found the holy grail. Instead, I found that to make money, first you have to have money and second, it is a lot of work. I found that it is actually easier and more profitable to be a trend trader, let the tail wind brings me to the warmer places.
