Wow,

The lack of pain and no Loss of Consciousness (LOC) mean little. The fact that you saw stars is enough to know right away you suffered a concussion. The delay in symptoms is not uncommon.

You missed one question, though.

I asked how many kids you have. You said a 3 and 7 year old. The correct answer should have been a 3, 7 and a man sized and aged child. Most boys never grow up.

My best to you.
