Interesting, the average life expectancy of an NFL player is 55, compare that to the average male of around 75.I doubt there has been an NFL player in the last 40 years who hasn't been on something.
"It is hard to put a price on the costs of the health problems related to steroids. We assumed that any additional medical costs would be covered by the players health care insurance, which we believe would be high quality given the strength of their employers and their union. However, we did attempt to quantify the financial effect of a shorter lifespan for a player.
It is not entirely clear how many years steroids take off of your life. Steroids unquestionably work extremely well--no denying it, says Dr. Harrison Pope of McLean Hospital in Belmont, Mass. But they will probably shorten your life expectancy. By how much, we still don’t know (Baily 2003). In order to make a guess at this effect, we first attempted to determine the average life expectancy of a Major League Baseball player. Unfortunately, we were not able to attain this data. We were able to determine that the average life expectancy for a football player in the National Football League is only 55 years (Neddenriep 2005). This lower life expectancy is surely due to the rigors of playing football. However, steroids are believed to also be a problem in the NFL, and some of this shortened life expectancy may be due to such drugs. The average life expectancy of an American male is 75 years (Schmid 2005). We therefore felt that a baseball player on steroids would be somewhere in between the average American male and an NFL player. We therefore conservatively chose five years as the effect of steroids on a players life expectancy. We then multiplied these five years times the pension earnings for a player. While we didnt know exact pension earnings, we did learn that a star player (Cal Ripken, Jr.) will earn $160,000 per year from his pension, so we used this figure as an approximation. Therefore, a player using steroids would lose $800,000 in future pension earnings"
