Happy New Year! I stumbled across the following YouTube classic over at grrlscientist's blog (which I heartily recommend). It's a wee bit long (a tad over 7 mins), and I don't do Spanish sadly - but it's all relatively self-explanatory. If you're not big enough to kill your prey straight-away - throw it off a cliff.
PS The patchlist isn't going very well due to it being dark while I go to work, and dark as I come back. Must try taking lunch outside.
