Seems true for me at least (1980 birth). One of my first friends died of a cat allergy at 12, another shot himself the next year at 13, my sister's best friend was murdered by her mom's boyfriend right after I graduated, my best friend from high school died from alcohol withdrawals in 2016, and it seemed like for a few years after high school, at least 1 or 2 people were dead from car accidents that I'd known from school every summer I came back from college. A guy I worked with in college broke his neck and died in basketball practice. Probably not fair to count people I met in my 20s since I was in the Army during the Iraq/Afghanistan years, but deaths were pretty regular. I wanna say my 20 year reunion had 12 deaths out of a graduating class of about 200? That isn't quite 9%, but doesn't count those who died before we graduated. And yeah, clearly the rate is likely to be much higher for people living in Bangladesh or Djibouti or something. I grew up in the Los Angeles suburbs.
