Understanding Your Body Type

I wonder if people still compare such things these days. I heard that at some clinics, they no longer make such distinctions, but when I was young, I was told that people should be classified as Taeyangin, Taeeumin, Soyangin, or Soeumin and eat the appropriate medicines or foods accordingly. I thought Taeyangin was the best, but it turns out to be the least common.. haha. Is there a way to find out my constitution?
