51 isn't young by any means. Maybe I am just skewed from having so many around me dying in early/mid 40s and being terminalish myself at 47.
I've been studying this some and it appears men go through a major chemical change in their 40s. It's usually when they get their first heart attack/stroke. If they are lucky like me they survive long enough to get on medications that gives them 1-30 more years, if not they die instantly. Men need full blood work and testing done through the 40s and 50s and it would save so many lives.
Could have been OD as well but I'm going to just guess the ticker misticked from blood thickening, heart issues or a rupture in the noggin. It kills way too many damn men and many that suddenly drop to the ground don't get the second chance.
Rip dude.
