Between WHO, CDC and several other scientific data sources, that record death by age do so in deaths per 1000 people in each age group. If you take the 35-65 age group as a whole, the years most "shocking" bodybuilding deaths occur, and average out the amount of people in this age range in the general population that die it's about 5-6 people per thousand that die every year. I would say there are at least 1000 bodybuilders around the world who do heavy gear in this age range, so 5 or 6 deaths per year is really not more than the general population.
