It would be a good idea if safety laws, such as speed limits, where constructed around formula with life expectancy as one of the variables. Plug in 70 years and get out 30mph. Plug in 140 years and get out 25mph. Since you are going to grow old and die anyway, spending too much time trying to avoid accidental death is self-defeating. Acknowledging this would provide a check on the tendency towards super-safety in public policy.
