Way too young. I'm 48 and remember everything about my "best friend" from my first few months of 1st grade. His name was Matt Molinaro and we were inseparable. Then one day he just stopped showing up. I don;t remember but I'm sure my parents made up daily excuses the next 3-4 months. But then one day they had to sit me down and tell me what Leukemia was. I remember every detail of that day.
Love and prayers to Karim's family, friends and teammates.
