The quality of life improvement from the added flexibility and strength must be taken into account also. To be a bit vulgar, would you rather engage in overnight activities with rock climber or with a couch surfer? Which one is able to run for the bus? Play with their kids? (a related issue that really annoys me is when they compare the dangers of ectasy and heroin using the death rate, when the quality of life destruction caused by ectasy is 1% compared to the horror that happens to a junkie)
