NOTE: A page like this should come with its own desalinization plant considering all the grains of salt that need to be taken with the inconclusive and generally stinky statistics presented here. Suffice to say that anyone heard to be drawing solid conclusions based on such surveys and studies as these is likely to be terribly wrong as well as deserving of a vigorous forehead slap. Be very careful with these and other publications that attempt to quantify the danger of cycling, of particular facilities, etc. Now get out there and twist twist twist those results to suit your various agenda, and remember, this is just a small fraction of the total amount of research out there.

OCCUPATIONAL INJURIES AMONG BOSTON MESSENGERS Harvard researcher J.
