Applying cold therapy to a tissue injury, helps limit the inflammation by causing the blood vessels to constrict. This in turn helps to limits the blood flow to the injured site, which helps to moderate the release of the vasoactive substances and therefore helps minimizes the pain and swelling in the injured area.
Kangaroos go down easy with well placed .22LR shots, so a .17HMR or .22WMR will not be a problem. I've got both a .17HMR and a .22WMR, I prefer the .17HMR mainly because it shoots flatter, making it better for rabbits, and will easily take a fox out to 120m at least (provided you placed your shots ;)).angaroos go down easy with well placed .22LR shots, so a .17HMR or .22WMR will not be a problem.

A new LD50 for nicotine. Prof Graz does not suggest a new LD50 (median lethal dose) for nicotine, but an estimate would appear to be 750mg (halfway between his opinion of the lethal dose minimum and maximum). This is more than 12 times the current figure of 60mg. new LD50 for nicotine.
