Not all risk aversion is worth the cost. We run into people all the time who tell us to change our lives to marginally decrease our risks. Examples would be telling pregnant women to not clean litter-boxes or to flip babies on their backsides to avoid SIDS. These proponents will never be able to give clear numbers for the benefits of their pet theories. But they will always say “better safe than sorry.”
To those who always say “better safe than sorry”, I often retort that they should dress their children in full riot gear because at any moment they can be hit by a meteor. The point is that not all risk is worth mitigating.
Well, it happens that a Florida child was struck by a meteor. Now I can add, “hey, because it has happened.”
