Here are some fun anecdotes that may shock a lot of non Americans (and some urban Americans):

My dad first took me shooting around 6 or 7 years old. I shot my first 12 gauge shotgun at around 10 or 11 years old, and I kept a deer rifle in my room from age 15(I didn't have ammo). At 17, I bought an AK47 semi-automatic rifle, and got my first handgun at 19. I regularly conceal carry a 9mm pistol and I don't have a license, though I do have training from a very young age and plan to get a conceal carry permit just because. I plan to raise my daughter similarly.

I live in rural Missouri. Most kids and young adults don't get an AK47, but otherwise my story isn't unusual around here.
