There seems to be a growing trend of generally healthy people looking for drugs/supplements to provide marginal improvements. I can't help thinking it's a sign of a vacuous and unfulfilling life. Instead of spending time and money on drugs to increase your life span, why not spend that time/money on actually living your life? I think this probably comes down to the general boredom that comes from not having a family and not having enough time off work to do anything else worthwhile.
