How many people younger then you do you know that have passed away

How many people do you know of that have passed away and they are younger then you? I am 33 and know lots of people who have died, its really a tragic thing. I know 3 guys in my class who died, two in car accidents, and the other fell into very cold water, and hit his head, and couldn't be rescued in time. They were all about 21. I used to babysit a girl and her sister and brother. She ended up dying at the age of 19 due to a brain anurisym. Another guy in his late 20's died in a four wheeler accident. Another guy, accidently shot himself, another guy who I didn't know personally but knew his family, he died in a training exercise for the military and he was only 20, and just this July, this same guys sister died in a car accident, she was 20 also. This family has lost two children in a matter of five years, they have another serving over in Iraq too.
Sorry to be so depressing, but I remember being young in highschool and councilors and teachers would talk about things and would say that we would end up losing someone from our class, we always felt like yeah right it won't happen to us, but it did and it does unfortanetly. But life goes on.
