I'm in my mid 60's and have lost 4 of the guys who I hung around with in grade school and high school already. Close friends, not just acquaintances. Mostly to alcohol/drug related health issues. There's five of us left, from that gang, hoping for the best.
Life is short, and it's not fair. In fact for many around the world it is extremely unfair. So live it the best you can. Make a difference.
