What does it mean when my eyebrow hair just falls out with a simple pull?

I am 28, male, slightly overweight, borderline diabetic, not too active but do go to the gym. I am not all that healthy, but I don't smoke or drink or ingest pills or sleep with sleazy women. Why is it that my eyebrow hair falls out out so easily? It's not necessarily falling out, but it comes out real easy, like its not even really attached. Not all the hair, but I am afraid that if I could pull them all out in a matter of minutes. Am I getting old? I guess my scalp hair is starting to come out more and more lately too.
