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.

Kangaroos may live anywhere from nine to 22 years on average. The life span of a kangaroo depends on the species and whether the animal lives in the wild or in captivity. The longest lived species of kangaroo is the giant red. Giant reds can grow up to 7 feet in height, and with that size comes an extended lifespan of up to 22 years. Eastern greys are the next longest lived, with a life expectancy of about 20 years in captivity. In the wild, they live between eight and 12 years. Western grey kangaroos have a similar lifespan to their eastern cousins with a life expectancy of 20 years in captivity and up to 10 years in the wild.
